Abstract

Sixteen black seeded soybean lines locally known as Kaley Bhatt, collected from different parts of Uttarakhand area of India were grown in similar environmental and field conditions along with five creamish-white colored control lines. Nutritional quality of seeds in terms of oil-protein quantity, fatty acid profile of seed oil and amino acid profile of proteins were established and compared. Kaley Bhatt accessions produced small sized black seeds with average hundred seed weight of 7.62 g. In general, black seeds were more in protein and less in oil content in comparison to creamish white colored seeds. Fatty acid profiles of the collections were uniform irrespective of seed color and size. Significant and negative association exists between oleic-linoleic and oleic-linolenic acid. Some black seeded accessions were identified for their higher concentrations of linolenic acid (omega-3 fatty acid). Essential amino acid composition of Kaley Bhatt accessions varied with in range of 47.75 to 40.73 mol% of total amino acid. Maximum methionine concentration of 2.08 mol % was observed in IC548683.
