Abstract

Trypsin inhibitors are one of the most important antinutritlonal factors in soybean [Glycine max (L.j Merrill.]. They decrease the digestibility of protein and cause pancreatic hypertrophy. Fifty-five soybean genotypes including Indian cultlvars were analysed for trypsin inhibitor activity (TIA). Mean TIA ranged from 14.49 mg g−1 seed meal to 29.05 mg g−1 seed meal. Genotypes PK-1042 (14.49) and EC-389178 (22.20) showed lower TIA mg g−1 seed meal. The studies showed no correlation of TIA with days to maturity, oil content, protein content and seed yield. Based on multivariate analysis, TIA showed maximum contribution to D2 value indicating scope for selection of parents in a breeding programme.
