The performance of the eight genetically diverse varieties of barley and their 28 Fis was evaluated to assess their genetic architecture for the yield and yield contributing traits in a set of diallel crosses. The component analysis indicated the presence of additive (B) and dominance (A and A2) genetic variances for plant height length of main spike and grain yield/plant. Ô component was higher than A, for plant height, number of grains/main spike and biological yield per plant. For remaining characters A was higher than B component, indicating the preponderance of dominance genetic variance. Over dominance was observed for days to reproductive phase, number of productive tillers/plants, length of main spike and grain yield/plant. Highly significant values of f were observed only for plant height indicating the predominance of dominant alleles. While highly significant values of fi2 were recorded for all the traits except days to reproductive phase revealing the predominance of dominant alleles.

Published: July 2023

Twenty chickpea genotypes were grown in six environments to study the phenotypic stability of grain yield and its components. It was found that the linear component of G x E interaction was more important for yield and other characters. Four genotypes i.e., SGM 84-104, IH 83-6, SG 2 and SGM 84-117 were found to have average response and high stability and high mean for grain yield. However, SGM 84-112 the highest yielding genotype was highly unstable. There was positive and significant correlation between the mean of the genotypes and the responsiveness for number of pods/plant, 100-grain weight and single plant yield which indicated that the genotypes with high mean were, in general, better responsive to favourable environments. There was lack of general association between stability of yield and its components which calls for cautious selection of genotypes based on yield alone.

Published: July 2023

Path analysis of seed yield was done in two sesame Sesamum indicum L.) varieties, JLT 26 and JLT 27 grown separately in acid soil (pH 4.0-5.5) under high rainfall mid altitude (1,000 m msl, 26°N and 92°E) conditions during the rainy (kharif) season of 1988. Seed yield was positively and significantly correlated with plant height, number of leaves, primary branches, length of main branch, number of capsules on main branch, number of capsules per plant, capsule length and seeds per capsule in both the varieties. Partitioning of total correlation coefficient of these characters with seed yield into the components of direct and indirect effects revealed that number of capsules per plant followed by seeds per capsule were the only two characters which contributed to seed yield directly. The direct contribution of rest of the traits was considerably low. However, their indirect contribution to seed yield through the number of capsules per plant was substantial. It is thus suggested that number of capsules per plant and seeds per capsule could be taken as indices while improving seed through selection..

The effect of fertilizer treatments (O, N, NP and NPK doses in kg/ha) on growth, productivity, insect-pest and disease incidence on rise in Gangetic alluvial soil (Entisol) of West Bengal under rainfed condition was evaluated in 1987 and 1988. The balanced fertilisation made highest increment on plant height, number of tillers, but phosphate fertilisation along with nitrogen exerted marked effect on dry matter production at panicle initiation stage. Increased number of matured panicles/m² due to NPK fertilisation resulted in higher grain and straw yield. Phosphorus along with nitrogen showed significant effect on number of filled grains/panicle and test weight. Nitrogen either alone or coupled with phosphorus exhibited higher degree of incidence of gall midge and yellow stem borer but NPK lowered the incidence of rice bug, leaf folder, gall midge and yellow stem borer. NPK increased the bacterial leaf streak infestation significantly than either of N or NP treatments.

The present study was undertaken on 34 genotypes of tomato (Lycopersicon esculentum Mill) to furnish the information of the nature of association among different yield attributes and their direct and indirect contribution towards yield. The coefficient of variation was high for plant height, number of fruits per plant and yield per plant in 34 accessions of tomato. Number of fruits perplant showed high heritability. There was a positive and significant association between yield per plant and number of fruits per plant. Path co-efficient analysis revealed that the direct effects via number of primary branches per plant, number of fruit clusters per plant and number of fruits per plant were positive but for number of primary branches per plant was of low magnitude. Hence it would be worth laying stress on number of fruit clusters per plant and number of fruits per plant while formulating selection programme in tomato.

To develop a mathematical model which can be used for prediction, one needs to have an assess of all variable pertaining to that system function. For water relation studies and to develop models, parameters like flow, leaf temperature, relative humidity, light intensity, diffusive resistance so also water/osmotic potential of leaf and soil, total transpiring area, their dynamics are prerequisites. However, during the present study, due to the lack of compatible apparatus to suit other measurements, no record could be made on a few parameters. And thus, a complete prediction equations could not be developed. Despite this fact, this investigation identified that flow and resistance have commendable relationship with transpiration than quantum and leaf temperature, changes in fertility levels bring non significant changes (sensu lato) intranspiration regulation, mothbean by exhibiting random variability indicates a complex mechanism involved in its transpiration regulation, warranting a detailed investigation.

General and specific combining ability variances and effects for seven fodder characters were studied in, bajra-napier interspecific hybrids obtained in line x tester programme involving 9 CMS lines of bajra as female and 6 genotypes of napier grass, as male. The mean squares due to general and specific combining ability were significant indicating the importance of both additive and dominance components. The magnitude of sca variances was greater than that of gca for all characters suggesting the predominance of non-additive gene action. The parents, 405 A, 306 A, and 732 A among the CMS lines of bajra and FD 466 and FD 435 among napier grass were identified as best general combiners. The crosses 306 A x FD 466, 306 Ax FD 435, 437 were the best specific combinations for forage yield. High heterosis observed for different forage yield characters was mostly due to the desirable sca effects.
