Burmese grape (Baccaurea sapida Muell. Arg.) belongs to the family Euphorbiaceae, is a minor underexploited fruit crop grown wild as well as under cultivation in Nepal, India, Myanmar, Bangladesh, China, Thailand, for fresh consumption. It is a dioecious plant and reported to have an excellent nutritive value, but mainly grown in homestead condition mostly in neglected ways without fullest utilization of its potentiality. The present study was aimed to understand and first time characterize the germplasm nature, and details of flowering and fruiting system of Burmese grape. The experiment showed that, tree growth habit and crown shape of all the accessions surveyed were semi erect and irregular, respectively. The flower bud differentiation in male and female accessions started during the mid February and anthesis occurred from mid March for both male and female accessions. The colour of the male flowers varied from yellow to green yellow shades while the colour of the female flowers varied from yellow to yellow green and green yellow shades. Significant variation of leaf area, number of flowers per panicle, length and diameter of inflorescence, fruit length, breadth, weight etc. were observed. The variation present on fruit length (2.81 cm to 3.80 cm), fruit weight (12.25g to 22.95g), pulp percentage (49.82% to 65.33%), total soluble solids (9.00º to 13.10ºBrix), tritable acidity (0.73mg to 1.28mg/100g fruit pulp) and ascorbic acid content ranged from (23.18mg to 57.80mg/100g fruit pulp) suggest suitable selection method for identification of promising Burmese grape genotypes.
