Abstract:
The soybean genotypes recorded significant variation for seed coat and biochemical parameters. In seed coat characters like seed coat proportion the genotype Birsa Soya 1 recorded highest proportion of seed coat (10.99%) followed by KDS 1274 (10.76%) and was found lowest 8.02% in KDS 1144 followed by KDS 1097 (8.23%). The highest seed coat hardness was recorded in Birsa Soya 1 (137.16 N) followed by KDS 1274 (128 N) and the highest seed coat thickness was recorded in genotype Birsa Soya 1(12.80 µm) and KDS 1274 (12.80 µm). In seed coat biochemical study the highest lignin content was recorded in black seeded genotype Birsa Soya 1(13.88%) followed by KDS 1274 (11.52%). Whereas the significantly lower seed coat lignin content of 4.26% was recorded in genotype KDS 1144 followed by KDS 1096 (4.41%). Highest peroxidase activity was also showed by black seeded genotypes Birsa Soya 1 (440.20ΔA min^-1 g^-1) followed by KDS 1274 (415 ΔA min^-1 g^-1). The lowest seed coat peroxidase activity of 223ΔA min^-1 g^-1 of fresh seed weight was recorded in genotype KDS 980 followed by RCS-11-07 (232.86ΔA min^-1 g^-1). It was observed that black seeded genotypes of soybean had higher seed coat proportion, lignin content, Peroxidase activity than that of yellow seeded soybean genotypes.
