Two distinct types, i.e. tall and dwarf types of phalsa, were studied for the differences in their physical parameters, chemical compositions and electrophoretic patterns of seed proteins by SDS-PAGE. The two types did not show any remarkable variation in their fruit weight, edible portion, seed weight and juice yield. Tall type had higher content of reducing sugars whereas total and non-reducing sugars were higher in drawf one. Qualitative analysis revealed the presence of sucrose and fructose in both the types whereas glucose was present only in tall one. Observed marked variations in the protein content of the fruit could be due to the differences in protein content of the seed rather than that of the pulp. Electrophoretic pattern of seed proteins revealed the complete absence of two protein bands of molecular weight 37, and 59 kD from the dwarf type.
