Inheritance of an Exposed Stigma Mutant in Alfalfa, Medicago Sativa L.1
Authors: Markus R. , Wilsie C. P. 
Published: July 2010

SynopsisTetrasomic inheritance of a single factor difference was postulated to explain F2 and backcross ratios from a cross involving normal × exposed stigma. Forty eight F1 plants were normal. Of 17 F2 progenies, 9 segregated approximately 35:1 and 8, approximately 3:1. Respective backcross; ratios were 5:1 and 1:1. Deviations from expected ratios indicated a deficiency of recessive genotypes, due possibly to partial selection against recessive gametes.
Two Additional Factors for Host Resistance to Net Blotch in Barley1
Authors: Mode C. J. , Schaller C. W. 
Published: July 2010

SynopsisEight varieties, 6 resistant to net blotch and 2 susceptible, were used as parents in the genetic studies reported in this paper. Three genes for resistance—Pt1, Pt2, and Pt3—differentiated the six resistant varieties from the susceptible varieties, Atlas and Atlas 46. Pt1 and Pt2 were tightly linked with about 2.57% recombination; Pt3 was inberited independently of the linked genes. The genes for net b'otch resistance were inherited independently of the Hanna gene for mildew resistance carried by Atlas 46.
Yield of Sudangrass Varieties as Affected by Time and Frequency of Cutting1
Authors: Burger A. W. , Jackobs J. A. , Hittle C. N. 
Published: July 2010

SynopsisFour Sudangrass varieties produced much less dry matter when harvested under the pasture system than when harvested under the hay system. Cutting date had no effect on the rank of the varieties in herbage production under hay management. Disease susceptible varieties tend to produce relatively less dry matter than disease resistant varieties, at the hay rather than the pasture system of management, and at the late rather than the early cutting dates within the hay system of management.
Influence of Timing of Irrigation on Yield, Quality and Fruiting of Upland Cotton1
Authors: Spooner A. E. , Caviness C. E. , Spurgeon W. I. 
Published: July 2010

SynopsisIrrigation increased the yield of cotton approximately 1 bale per acre but water applied before blooming had no beneficial effect. Maturity was delayed and the peak of fruiting was extended 2 weeks by irrigation. Shedding was significantly decreased and boll size was significantly increased. Lint quality was improved in most cases by proper moisture conditions.
The Inheritance of Inflorescence Type, Peduncle Length, Flowers Per Node, and Percent Flower Shedding in Soybeans1
Authors: van Schaik P. H. , Probst A. H. 
Published: July 2010

SynopsisOne factor pair conditioned type of inflorescence. The gene for pedunculate was dominant over sub‐sessile inflorescence. The symbols Se and se have been assigned to this factor pair.Inflorescence type segregated independently of flower color and growth type but was linked with maturity and height.Peduncle length, flower number per node, and percent flower shedding were inherited quantitatively with dominance and complementary gene effects toward long peduncles, high flower number, and high shedding.
Root Anatomy and Growth Habit of Some Alfalfa Varieties in Relation to Wilt Resistance and Winter‐hardiness1
Authors: Seth Jagdish , Dexter S. T. 
Published: July 2010

SynopsisIn no way could the anatomy of the wilt resistant varieties of alfalfa be differentiated from that of the susceptible varieties. Short days caused a notable decrease and recumbence in top growth of the winter‐hardy varieties. The annual growth rings of the field‐grown roots of hardy varieties revealed formation of large xylem vessels during long days and small xylem vessels during shorter days. The same contrast in vessel size was seen in the greenhouse‐grown roots of hardy varieties but it was less prominent in nonwinter‐hardy varieties.
Moisture Relations in Soft Red Winter Wheats. I. Varietal Differences and Delayed Harvest Effects1
Authors: Pool Mart , Patterson Fred L. 
Published: July 2010

SynopsisFour varieties of soft red winter wheat differed in rate of drying to the 14% moisture level in the field after rains or dews. Rates of moisture gains and losses in the laboratory increased during the delayed harvest period and were related to internal changes in kernel structure. Varieties differed in rate of change in absorption properties during the delayed harvest period.
Variability in Nutrient Uptake and Yield of Clonally Propagated Kenland Red Clover1
Authors: Seay William A. , Henson Lawrence 
Published: July 2010

SynopsisDry matter yield, total uptake of soil and fertilizer P, utilization of fertilizer P mixed through the soil or topdressed and uptake of soil and, fertilizer K varied much more among 30 clones of Kenland red clover than among replicates of clones. These same properties varied widely among 10 clones selected for longevity. It appears that plant yield or uptake of nutrients by clover or like plants can be measured more precisely by using all plants propagated from the same clone than by using seed which vary in genetic character.
Genes for Stem Rust Resistance in Kenya Farmer Wheat1
Authors: Aslam Mohammed , Ausemus E. R. 
Published: July 2010

SynopsisIn crosses of Kenya Farmer with Marquis, Kentana, and Lerma, the mature plant reaction to a collection of races of stem rust in the field appeared to be inherited on a relatively simple basis, with resistance dominant. The F3 seedling reactions to stem rust race 15B indicated an interaction of 3 independently inherited genes for resistance and 2 epistatic genes for susceptibility. Seedling reaction to races 38 and 11 were the same except there was only 1 susceptible gene.
Comparison of Different Generations of Soybean Crosses Grown in Bulk1
Authors: Torrie James H. 
Published: July 2010

SynopsisAmong soybean crosses grown in bulk, a differential response occurred for seed yield but not for plant height, lodging index, or relative maturity when the same generation was tested in different years. However, crosses responded similarly for all characters when different generations were tested concurrently using seed of the same age. Crops grown from 2‐ and 3‐year old seed were lower in yield and slightly later in maturity than those grown from 1‐year old seed.
Treating Irrigated Sorghum with 2,4‐D1
Authors: Wiese A. F. , Rea H. E. 
Published: July 2010

SynopsisSorghum at the flowering stage was susceptible to all rates of 2,4‐D. Applications of ½ pound per acre of either 2,4‐D ester or amine did not reduce yields of sorghum at other stages of growth. One or two pounds of 2,4‐D per acre supplied immediately after irrigations tended to reduce sorghum yields.
Growth, Maturity, and Yield of Corn as Affected by Chloride in Potassium Fertilizer1
Authors: Younts S. E. , Musgrave R. B. 
Published: July 2010

SynopsisHigh concentrations of chloride attained in row fertilization had adverse effects on corn growth, maturity, and yield. Broadcasting or mixing the chloride with soil tended to alleviate these effects. Low chloride applications, common in hill or row fertilization with KCI, were not detrimental but generally beneficial.
Effect of Pot Size and Shape on Yield and Phosphorus Uptake of Millet1
Authors: Armiger W. H. , Fried Maurice 
Published: July 2010

SynopsisSmall containers produced the largest yields based on a ratio of plant population to weight of soil. Generally, for greenhouse experiments relatively small containers not only offer an economy in quantity of soil and greenhouse space needed, but actually give comparable yields per unit weight of soil.
A Comparison of Birdsfoot Trefoil‐Bluegrass and Ladino Clover‐Bluegrass for Pasture: II. Yield of Herbage and Relationships to Lamb Response
Authors: Davis R. R. , Bell D. S. 
Published: July 2010

SynopsisWhen measured by cages, European birdsfoot trefoil‐bluegrass pastures yielded more dry matter than Ladino clover‐bluegrass. Rotational grazing generally resulted in higher yield and the nitrogen content of the herbage was higher than with continuous grazing. The yield of dry matter was closely correlated with animal carrying capacity (r = 0.811). Herbage yield and animal gain per acre were not related.
Air Pollution With Relation to Agronomic Crops: II. A Bio‐Assay Approach to the Study of Air Pollution
Authors: Noble Wilfred M. , Wright Lloyd A. 
Published: July 2010

SynopsisPoa annua (annual blue grass) has been studied and used to determine the relative intensity of the primary phytotoxicant in the Los Angeles smog. Petunia (Rosy Morn) has been used in addition in order to increase the reliability of the diagnosis. A standard technique has been developed for the use of these materials. This method has been in continuous operation since October 1954.
Growth of Alfalfa, Red Clover, and Birdsfoot Trefoil Seedlings Under Various Quantities of Light1
Authors: Gist George R. , Mott G. O. 
Published: July 2010

SynopsisAlfalfa, red clover, and birdsfoot trefoil seedlings gave a linear growth response to light treatments ranging from 2,400 to 14,400 foot‐candle‐hours per day. During the period from 41 to 56 days after seedling emergence, under the highest light treatment, red clover made 20% more top growth and 50% less root growth than alfalfa. Under the lowest light treatment the top growth of red clover was approximately twice that of alfalfa.
The Heritability of Reaction in Alfalfa to Common Leafspot1
Authors: Adams M. W. , Semeniuk G. 
Published: July 2010

SynopsisEstimates of heritability of family differences in reaction to Pseudopeziza medicaginis ranged from 79.26 to 89.62% in 2 unrelated alfalfa populations. The heritability of individual differences was lower, amounting to 27.4% in the one population for which it was calculated. Excellent agreement was obtained among four estimates of genetic variance for leafspot reaction in the case of one population.
The Influence of Oat Stubble Management on the Establishment of Alfalfa and Red Clover1
Authors: Klebesadel L. J. , Smith Dale 
Published: July 2010

SynopsisEstablishment was improved by clipping stubble close to the soil surface in late July after grain harvest, especially where the oats had been sprayed to control weeds. Clipping benefited red clover more than alfalfa. Clipping in late August was usually beneficial when moisture was abundant but was harmful under low‐moisture conditions. Raking after clipping was beneficial to alfalfa but was usually detrimental to red clover except after August clipping when moisture was abundant.
Growth Response of Alfalfa Seedlings Under Various Light Regimes1
Authors: Bula R. J. , Rhykerd C. L. , Langston R. G. 
Published: July 2010

SynopsisDry weight accumulation in alfalfa seedlings was essentially proportional to light intensity when grown under 750, 1500, and 3000 f‐c. and a 15‐hour photoperiod. A high light intensity period followed by a low intensity period resulted in greater dry weight accumulatlon than an inverse light regime even though the total amount of incident energy was the same.
Multiple Variation Including Crown Rust Resistance in Irradiated Floriland Oats1
Authors: Chapman W. H. , Luke H. H. , Wallace A. T. , Lunden A. O. 
Published: July 2010

SynopsisExtreme variation in morphological characters and pathological reaction was observed in progenies from irradiated Floriland oats. When inoculated with crown rust race 264 under greenhouse conditions, a mesothetic reaction and a distinct mature‐plant resistance were observed. Resistance to crown rust race 264 and race 290 was found under greenhouse conditions and to race 264 under widely different field conditions.
Combining Ability for Seed Characteristics in Bromus Inermis Leyss1
Authors: Nielson A. K. , Kalton R. R. 
Published: July 2010

SynopsisExtensive variation and segregation for combining ability for seed yield, panicle number, fertility, and seed weight were observed. One generation of inbreeding had no effect on combining ability for seed yield or weight, but decreased fertility somewhat. Panicle number and fertility were the primary components of seed yield, while seed weight was unrelated to these. Heritability of combining ability for fertility and seed weight was relatively high, but only moderate for seed yield and panicle number. Forage and seed yield were positively correlated but predictive value was low.
Relationship of Beef Gains to Forage Yields1
Authors: Schultz E. F. , Langford W. R. , Evans E. M. , Patterson R. M. , Anthony W. B. 
Published: July 2010

SynopsisAnnual acre beef gain is related to annual acre forage production. The relationship is quadratic and may be used for estimating differences in annual beef gain per acre among treatments evaluated as to forage production under grazing conditions in the same experiments. The difference‐estimating equation is:

D = 0.071,18 (X1 − X2) − 0.000,001,732 (X12 − X22), where X1 and X2 are the average annual acre yields in pounds of oven dry forage for the two treatments.
The Zebra Leaf Character in Alfalfa and Its Dosage‐Dominance Relationship1
Authors: Stanford E. H. 
Published: July 2010

SynopsisThe character zebra leaf in alfalfa is dependent on a single tetrasomic gene with dominance at the duplex level. The tetrasomic duplex‐dominant system differs rather markedly from the simplex‐dominant system in the proportion of dominant plants in successive generations of inbreeding. This would be reflected in a different rate in the decline of hybrid vigor in inbreed generations.
Estimation of Available Soil Potassium from Plant Analyses1
Authors: Phillips M. W. , Barber S. A. 
Published: July 2010

SynopsisResults from greenhouse and field experiments indicate that total potassium uptake is a more precise measurement of available soil potassium than is the percent potassium in the whole plant or in the sixth leaf. Total uptake of potassium varied less with variations in nitrogen, phosphate and plant weight than did percent composition.
Development of Axillary Buds in Maize in Relation to Barrenness1
Authors: Sass John E. , Loeffel Frank A. 
Published: July 2010

SynopsisThe formation of floral organs in maize is not prevented by dense planting. Competitive pressure does not produce a marked retardation of ear elongation, ovary development, or silk elongation until approximately 74 days after planting. Barrenness is the result of failure of silk emergence during the pollen‐shedding period.
Lodging Resistance Studies in Oats. II. Inheritance and Heritability1
Authors: Frey K. J. , Norden A. J. 
Published: July 2010

SynopsisLodging resistance in oat crosses as measured by the cLr method appeared to be genetically controlled. Heritability percentages were 19, 6, and 15, respectively, for the F2–F3, F2–F4, and F3–F4, comparisons. Considerable variability for lodging resistance was found among lines selected from Clintland variety.
Effect of Depth of Water Table on Yield of Ladino Clover, Orchardgrass, and Tall Fescue1
Authors: Gilbert W. B. , Chamblee D. S. 
Published: July 2010

SynopsisWithout surface watering, Ladino clover, orchardgrass, and tall fescue produced 20, 54, and 71% more, respectively, with 6‐inch water tables, than with 12‐ and 20‐inch water tables. With 1 inch of surface water per week, a large increase in yields was obtained with the lower water tables, and a depression with the 6‐inch water tables. With surface watering, the depths of water tables had little effect on the yield of Ladino clover.
Relationship Between Botanical Composition, Nitrogen Response, and Water Table Level on Wet Meadow Sod1
Authors: Klages M. G. , Asleson J. A. 
Published: July 2010

SynopsisControlled water level and nitrogen fertilizer treatments on native wet meadow sods grown in large drums greatly altered the botanical composition of these sods over a 3‐year period. Changes in the botanical composition accounted for much of the effect of these treatments on yield. Treatments favoring sedges and forbs gave low yields, while treatments favoring grasses produced high yields.
N and P Composition and Yield of Corn as Affected by Fertilization1
Authors: Reichman G. A. , Grunes D. L. , Carlson C. W. , Alessi J. 
Published: July 2010

SynopsisCorn yield and N and P percentages were increased by fertilization with N at rates up to 80 pounds per acre together with P at 22 pounds per acre. The yields were highly correlated with the N percentages in the corn leaves. Critical N levels were calculated from the data.
Evaluation of Cool‐Season Turfgrasses Alone and In Mixtures1
Authors: Juska F. V. , Hanson A. A. 
Published: July 2010

SynopsisA mixture of 75% Merion Kentucky blue‐grass with 25% red fescue and mixtures of common Kentucky bluegrass with red fescue produced a higher quality turf in 1958 than either of the bluegrasses seeded alone. Merion seeded alone was superior to mixtures of Merion‐common and Merion‐red fescue the first 4 years, 1954–57, after which this variety was seriously injured by stripe smut.
Varietal Differences in the Rotenoid Content of Tephrosia vogelii1
Authors: Irvine J. E. , Freyre R. H. 
Published: July 2010

SynopsisThe mean rotenoid content of 16 introductions of Tephrosia vogelii was found to vary from 0 to 2.9% dry weight. Mean differences were observed at the 1% level of probability in rotenoid content, plant height and width, leaflet number and size, and flower color. No differences were observed in leaf nitrogen content. A negative correlation was found between mean leaf rotenoid content and mean plant height.
Bindweed (Convolvulus arvensis L.) Control and Seedling Emergence as Affected by Tillage, 2,4‐D, and Competitive Crops1
Authors: Wiese A. F. , Rea H. E. 
Published: July 2010

SynopsisBindweed on noncropped areas was controlled in 5 years with 2 annual applications of 2,4‐D or by sweep tillage at 10 and 15 days after weed emergence. On winter wheat land bindweed was controlled with several combinations of sweep tillage and 2,4‐D applications. Emergence of bindweed seedlings from the soil was reduced when application of 2,4‐D was used exclusively for bindweed control.
The Response of Alfalfa Varieties to Photoperiod, Color of Light and Temperature1
Authors: Nittler L. W. , Gibbs G. H. 
Published: July 2010

SynopsisSeedlings of southern and northern types of alfalfa varied in their response to photoperiod, color of light, and temperature. The greatest difference in growth between these types occurred with short photoperiods, a combination of red and green light, and low temperatures.
Evaluation of Characters in Polycross, Inbred, and Open‐Pollination Progenies of Timothy1
Authors: Nielsen E. L. , Smith D. C. 
Published: July 2010

SynopsisPolycross, S0 and S1 progenies selected for superior vigor, leafiness, and resistance to foliage diseases were studied to determine the effectiveness of inbreeding as a breeding technique in a timothy improvement program. The results suggest that for strain improvement, extensive reselection of superior plants from large open‐pollination populations might be equally effective and more economical than would inbreeding and selection during initial stages of the breeding program.
The Lignin Content of Grass Strains1
Authors: Sosulski F. W. , Patterson J. K. , Law A. G. 
Published: July 2010

SynopsisSignificant differences in lignin content among 22 strains of 4 grass species at the flowering stage of growth are reported. The relative lignin content of strains is influenced by stage of growth, location, proportion of plant parts, and their rates of lignification.
Role of the Male Gametophyte in Dallisgrass Reproduction1
Authors: Wilson J. A. , Holt E. C. 
Published: July 2010

SynopsisPollination is necessary for seed set in common and yellow‐anthered dallisgrass. Although common has a high percentage of aborted pollen, there appears to be enough functional pollen for good seed set. Growth of pollen tubes into the ovule of common and yellow‐anthered dallisgrass is a prerequisite for endosperm formation. Pollination is not essential for embryogenesis in common but is necessary in the yellow‐anthered type.
Rock Phosphate and Superphosphate as Sources of Phosphorus and Calcium for Alfalfa1
Authors: Thurlow D. L. , Smith F. W. 
Published: July 2010

SynopsisIn a greenhouse experiment, yields were increased by application of lime alone, superphosphate alone, and in some cases by rock phosphate alone. Lime was a better source of Ca for alfalfa than was rock phosphate.
Autotetraploidy and Linkage in Alfalfa— A Study of Resistance to Two Species of Root‐Knot Nematodes1
Authors: Goplen B. P. , Stanford E. H. 
Published: July 2010

SynopsisResistance to two species of root‐knot nematodes (Meloidogyne hapla and M. javanica javanica) in an alfalfa clone selected from Vernal is controlled by single dominant tetrasomic genes for each species. The genes governing resistance to the two species are different but closely linked. One other Vernal selection shows resistance to both species and a third Vernal selection and one from the California Common strain Hilmar show resistance only to M. hapla. Genetic data are less conclusive for these clones, but inheritance seems to be relatively simple.
Comparison of Ladino and Louisiana White Clovers in Three Grass Sods1
Authors: Craigmiles J. P. , Crowder L. V. 
Published: July 2010

SynopsisLadino types of white clover were superior to intermediate types in forage production, percent crude protein, and persistency. They also contributed a higher proportion to the grass‐legume mixture. These findings were the same whether the clover was grown alone, with a grass, under irrigation, or without additional water. Only in seed production were the intermediate types superior to the Ladino types.
Combined Effects of Glandless Genes gl2 and gl3 on Pigment Glands in the Cotton Plant
Authors: McMichael Scott C. 
Published: July 2010

SynopsisTwo genes, gl2 and gl3, were found responsible for glandlessness (absence of pigment glands) in the cotton plant, Gossypium hirsutum L. A third gene, gl1, is inherited independently and is masked by the action of gl2 and gl3. Glandlessness is recessive in the seedling stage but partially dominant in the mature stage. Glandless cottonseed, previously found associated with absence of gossypol and other pigments, promises to be of economic value to the cottonseed crushing industry.
Modification of Some Physical Characteristics of Soils with VAMA, Ferric Sulfate, and Triphenylsulfonium Chloride1
Authors: Pugh A. L. , Vomocil J. A. , Nielsen T. R. 
Published: July 2010

SynopsisAlthough triphenylsulfonium chloride (TPS‐Cl) produced only small changes in water stable aggregation and hydraulic conductivity, it reduced the modulus of rupture values appreciably on all soils tested. Modulus of rupture values obtained from soils treated with TPS‐Cl were equal to or lower than those obtained from soils treated with ferric sulfate or VAMA.
Yield and Mineral Content of Corn as Affected by Ammonium Chloride Fertilizer1
Authors: Teater R. W. , Mederski H. J. , Volk G. W. 
Published: July 2010

SynopsisYield of corn fertilized with NH4Cl was not significantly different from corn fertilized with other common nitrogen carriers. Increased absorption of Cl by plants did not alter the plant content of other mineral elements. Spring‐applied Cl was largely leached from the soil by the following spring.
Influence of Stubble Mulching on Organic Matter and Nitrogen Content of the Soil1
Authors: Norstadt Fred A. , McCalla T. M. 
Published: July 2010

SynopsisIncreases in readily oxidizable organic matter, carbon, and nitrogen with stubble mulching for 14 and 19 years ranged from 5 to 10% and were concentrated in the surface inch of soil. There were no measurable differences between tillage treatments at depths of 1 to 6 and 6 to 12 inches.
