Abstract

Nine land races of country bean from North east India were evaluated for nutritive
values and seed protein profile was analyzed for molecular characterization. The tender
pods, which are used as vegetable, had crude protein in the range of 16.44 to 21.47%. Total
carbohydrate varied from 14.53 to 19.61%. Lipid occurred in the lowest proportion; in the
range of 0.43 to 0.96%. The range of variation for crude fiber was 13.53 to 21.47% while for
ash content the range was 6.23 to 9.17%. On the other hand, protein and carbohydrate
content of mature seeds were much higher than the corresponding values for tender pods.
Protein content of mature seeds varied from 23.99 to 35.51% while the range for carbohydrate
was 28.18 to 48.41%. Lipid content varied from 0.76 to 1.93%. Crude fiber contents were
lower than the corresponding values for tender pods and varied from 10.52 to 16.77%.
Range of variation for ash content was 5.13 to 9.19%, which is nearly same as that of tender
pods. SDS-PAGE analysis of seed protein revealed the presence of a total 30 bands and
dendrogram analysis indicated the presence of 2 clusters. 6 protein bands, viz. 31.5, 32.2,
33.6, 40.0, 54.0 and 61.3 Kd were found in all the land races and could be considered as
protein molecular marker for the species.
