Abstract

Seed fractions of twenty varieties of Vigna radiata (L) Wilczek of varying sizes were examined for protein and starch contents using micrckjedahl and Anthrone methods, respectively. Ten varieties are yellow seeded and the other ten are green seeded. Protein content was found to range from 19.1 to 25.1% and starch from 38.6 to 48.8%. The major portion of these nutrients are localized in the cotyledon, protein content ranges from 18.7 to 25.1% and starch content from 38.6 to 47.6%.

Seed color and seed size were observed to have no association with protein content. Seed color was noted to have no effect on starch content. However, a significant seed size effect was detected. A definite trend for the big seeded varieties to higher starch content than the small seeded varieties was observed.

A non-significant negative correlation coefficient value (r__0.296) was found between protein and starch contents.
