Title: Mango tree named ‘B74’

Description:
Latin name of the genus and species of the plant claimed:  Mangifera indica.    
   Variety denomination: ‘B74’. 
   BACKGROUND AND SUMMARY OF THE INVENTION 
   This invention relates to the discovery and asexual propagation of a new variety of mango tree, as herein described and illustrated. The new variety was first hybridized by controlled pollination. The new variety is a precocious, heavy-cropping, upright tree yielding red-skinned, medium-sized, terpinolene-flavored fruit. 
   The seed parent is ‘Sensation’ and the pollen parent is ‘Kensington Pride.’ The new variety was selected and evaluated at the fruiting stage on the property of Mr. And Mrs. L. W. Dorrian at Childers, in Queensland, Australia. 
   The new mango tree variety was first asexually propagated by grafting onto seedling rootstocks in Childers, in Queensland, Australia. 
   The new mango tree variety cv. ‘B74’ has been shown to maintain its distinguishing characteristics through successive asexual propagations.

   DETAILED BOTANICAL DESCRIPTION OF THE INVENTION 
   Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech, is aptly descriptive. 
   The descriptive matter which follows pertains to ‘B74’ mango trees (as well as the comparative varieties ‘Sensation,’ ‘Kensington Pride’, and ‘R2E2’, each of the foregoing which is unpatented) grown in the vicinity of Childers, Queensland, Australia. The scions of the candidate and comparator varieties were topworked to ‘Keitt’ trees (unpatented) that were originally grafted to polyembryonic seedlings of ‘Kensington Pride.’ Ten single tree replicates of each cultivar were planted at 6×10 m intervals in red basaltic soil (kraznozem) following a completely randomised design. Pest and disease treatments were applied as required. Irrigation and fertilizer application followed commercial practice. 10-20 random measurements of each characteristic were obtained from each replicate. Redness of skin color was determined using a Minolta Chroma Meter CR-200 to measure the hue angle (H). Mean values were taken from measurements at three points from the shoulder to the basal end of the sun-exposed side of each fruit. The lower the hue angle, the greater the red coloration. The observations described herein are believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere. 
   Ten single tree replicates of each cultivar were planted at 6×10 m intervals following a completely randomised design. The trees were grown on a red basaltic clay loam (kraznozem) near Childers in south east Queensland, Australia (latitude 25° S., altitude 40 m). Irrigation was available to supplement the average rainfall of 900 mm. Daily light interception (measured as photosynthetic photon flux) by tree canopies during the period of fruit development (October to February) ranges from 15.5 to 59.5 mol quanta m −2  at this site. The mean annual maximum/minimum temperatures at this site are 24/15° C. (Australian Bureau of Meteorology). 
   Pest and disease treatments were applied as required. Irrigation and fertilizer application followed commercial practice. 10 to 20 random measurements of each characteristic were obtained from each replicate. 
   Redness of skin color was determined using a Minolta Chroma Meter CR-200 to measure the hue angle (H). Mean values were taken from measurements at three points from the shoulder to the basal end of the sun-exposed side of each fruit. The lower the hue angle, the greater the red coloration. Elsewhere throughout the specification, color references are made to The Royal Horticultural Society Color Chart. The observations described herein are believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere. 
   The new mango tree cultivar, ‘B74’ is quite distinct from its seed parent ‘Sensation’, and may be distinguished from its seed parent in the following characteristics: The average fruit weight of ‘B74’ (457 g) is larger than ‘Sensation’ (360 g). Additionally, the new mango tree cultivar matures 3-4 weeks earlier than the seed parent ‘Sensation’, which is a very late variety. The skin color of the new mango tree cultivar is red and yellow, while the skin color of the seed parent ‘Sensation’ has a bright yellow background with a dark red to purple blush that covers most of the surface. Further, while the new mango tree cultivar has a terpinolene aroma in both the leaves and fruit, the seed parent ‘Sensation’ has no distinguishable terpinolene aroma in either leaves or fruit. 
   The new mango tree cultivar may be distinguished from the pollen parent, ‘Kensington Pride,’ by the following characteristics. The tree of the new mango cultivar ‘B74’ has a more erect form and lower vigor than the tree of the pollen parent ‘Kensington Pride’. The fruit of the new mango tree cultivar matures in late season, while the fruit of ‘Kensington Pride’ matures early to mid-season. The predominant skin color of ripe fruit of the new mango tree cultivar is approximately equal amounts of yellow and red blush (approximately 30% to 55% red blush), while the predominant skin color of ripe fruit of ‘Kensington Pride’ is yellow with a small proportion of red blush. The fruit flesh of the new mango tree cultivar is pale yellow in color, while the fruit flesh of ‘Kensington Pride’ is yellow. The fruit shape of the new mango tree cultivar is broad elliptic, while fruit shape of the pollen parent ‘Kensington Pride’ is medium elliptic. The sinus proximal of the stylar scar of the new mango tree cultivar is absent, while it is present in the pollen parent ‘Kensington Pride.’ The fruit of the new mango tree cultivar is somewhat smaller than that of ‘Kensington Pride’ (457 g as compared to 475 g). The seed of the new mango tree cultivar is of the monoembryonic type, while the seed of the pollen parent ‘Kensington Pride’ is polyembryonic. 
   The new mango tree variety ‘B74’ may be distinguished from presently available cultivars. The new mango tree cultivar ‘B74’ can be compared, for example, to ‘R2E2’, which is commonly grown in Australia, by the following distinguishing characteristics: The leaves of the new mango tree variety are shorter and wider than the leaves of ‘R2E2.’ The new mango tree cultivar has a higher percentage of bunch bearing inflorescences than ‘R2E2.’ The fruit of ‘B74’ is smaller than that of ‘R2E2.’ The flesh color of the new mango tree variety is pale yellow, while the flesh color of ‘R2E2’ is yellow. The skin color of ripe fruit of the new mango tree variety is approximately equal amounts of yellow and red blush (approximately 30% to 55% red blush), while the predominant skin color of ripe fruit of ‘R2E2’ is predominantly yellow with a small proportion of red blush. Additional comparative information can be found in Table 1. 
   TREE 
   
       
       General:
             Vigor. —Low to moderate. Fruiting B74 mango trees growing at the experimental site typically produce only one flush of shoot growth annually following the completion of fruit harvest in early February. Autumn/winter temperatures typically restrict further vegetative growth prior to flowering in September—October. The mean length of summer shoot growth is approximately 26.5±2.4 mm (± values are the standard error of the mean).     Height and spread of tree. —At the time the description was made for Plant Breeders Rights in Australia the trees were 3 m high with a spread of 3.5 m. However, these trees were top-worked to existing 6-year-old trees. More typically nursery-produced ‘B74’ trees grafted to ‘Kensington Pride’ seedling rootstock reach approximately 1.25 m diameter and approximately 1.5 m in height by their third flowering anniversary after planting which is their first year of commercial cropping at Childers in SE Queensland.     Density of foliage. —Open.     Shape. —Upright.     Form. —Erect.     Fruit bearing. —Mid-late season maturity. Fruit maturity of ‘B74’ is generally reached after the accumulation of 1650 degree days (measured by the number of °C. hours accumulated above 10° C. starting from the point of full inflorescence extension). At the site where the description for ‘B74’ was developed, fruit reached the mature green stage during the first week of February (midseason).     Root stock. —‘Kensington Pride’.       
     
       Trunk: The top-worked trees used for the original description for Plant Breeders Rights in Australia did not have ‘B74’ trunks, as they were top-worked onto ‘Keitt’ trees as described above. However, the trunk data supplied below have been collected from another block of 10-year-old ‘B74’ trees in the same orchard where ‘B74’ was grafted directly to seedling ‘Kensington Pride’ rootstocks. The position where the diameter was measured is above the graft union.
             Mean diameter of trees measured  50  cms above ground level. —Approximately 19.3±0.3 cm.     Trunk color. —About Grey-brown 199A.     Bark texture. —Slightly rough with slight vertical ridges 10 to 20 mm apart.       
     
     
  
   BRANCHES

Inflorescence length. —Approximately 319.7±9.6 mm.     Inflorescence diameter at the widest point. —Approximately 175.8±5.3 mm.     Inflorescence rachis color. —About Red 47C.     Inflorescence texture. —The rachis of the inflorescence moderate pubescence.     Mean number of inflorescences per tree. —Approximately 316.8±27.2.     Mean number of flowers per inflorescence. —Approximately 764.0±32.7.     Date of first and full blooms. —Variable. Flowering dates vary between years and are typically influenced by the size of the preceding crop, the time that floral induction temperatures occur in the autumn/early winter and the temperatures received during the latter part of winter. Typically at the Childers site inflorescence bud break occurs in mid to late July but full bloom does not occur until the second to third week in September. To calculate Heat Accumulation Units to determine fruit maturity the time of full bloom in September is used.
