✦ Synopsis

Low trypsin inhibitor (LTI) and chymotrypsin inhibitor (LCTI) mutants have been identified and isolated from the M, mutant lines of winged bean. The LTI and LCTI lines demonstrated a true breeding feature in the subsequent generations. Three to five isoinhibitor bands of trypsin and chymotrypsin were absent in different mutants, indicating mutations in the respective gene loci. The LTI and LCTI mutants inhibited insect gut proteases as efficiently as their control counterparts. This could be attributed to a specific group of inhibitors present in all the mutant types.

## Abstract The protein, trypsin inhibitor and lipid of the seeds from 15 New Guinea and 15 Thai winged bean varieties grown in Malaysia were analysed. The results show that winged bean seeds have a high protein content, ranging from 27.8 to 47.2% (based on dry seed wt). The trypsin inhibitor conte
