Morphological and physicochemical characterization of Burmese grape (Baccaurea ramiflora Lour.)

Abstract

Burmese grape (Baccaurea ramiflora Lour.) is a popular minor fruit in Bangladesh. Morphological and physicochemical characterization of Burmese grape was conducted at Pirujali, Gazipur during 2017-18 in eighteen Burmese grape genotypes. Wide variation was observed in case of growth, yield contributing characters, yield and fruit quality of the germplasm studied. Correlation study among different growth parameters of the genotypes was done to know the relationships so that superior genotypes can be se- lected for further experiment. Fruit set (%) was the highest in BS09 (77.27%) genotype and the lowest was in BS02 and BS03 and it was 36.84%. Zero percent fruit drop was observed in BS06, BS07 and BS17 and the highest fruit drop was in BS08 (50%) genotypes. The days to fruit maturity was the lowest (100 d) in BS12 genotype followed by BS13 (103 d) and the highest maturity days was in BS18 (132 d). For most of the desirable attributes BS02 showed better response such as maximum leaf length (28.31 cm), leaf breadth (9.02 cm), fruit length (34.1 mm), fruit diameter (33.9 mm), juice content (38 mL 20 seeds⁻¹), total soluble solids (18%), and ascorbic acid (13.2 mg 100g⁻¹). BS03 ranked the second among the genotypes on the basis of these parameters. Fruit number had negative correlation with fruit length, single fruit weight and juice content.
