Genetic variability for trypsin inhibitor content in soybean [Glycine max (L.) Merrill.] and its correlation with oil and protein

Published on

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 0
