Appraising components of genetic variation and estimation of micronutrients and antinutrient parameters in black gram (Vigna mungo L.) genotypes

Abstract

A study was conducted to evaluate 30 black gram (Vigna mungo L.) genotypes for genetic variation in micronutrients and anti-nutritionalfactors. All the genotypes exhibited significant genetic variability for protein content (16.19–31.07%), iron (60.98–95.50 ppm), zinc(35.89–44.01 ppm), and selenium (1.12 to 19.53 ppm). Four genotypes, namely, PU-15-21 showed higher values for protein, PU-15-30for iron, PU-KUG21 for zinc, and PU-8 for selenium contents. Phytic acid content ranged from 0.09 to 5.65 mg/g, with PU7 exhibiting thelowest. Correlation analysis indicated positive relationships between protein and seed yield iron and zinc contents. A few genotypesshowed higher micronutrient levels and seed yield along with lower phytic acid, suggesting their potential for breeding aimed atenhancing micronutrient content and yield with low phytic acid levels in black gram.
