Appraising components of genetic variation and estimation of micronutrients and antinutrient parameters in black gram (Vigna mungo L.) genotypes
Main Article Content
Abstract
A study was conducted to evaluate 30 black gram (Vigna mungo L.) genotypes for genetic variation in micronutrients and anti-nutritional
factors. 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-15-30
for 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 the
lowest. Correlation analysis indicated positive relationships between protein and seed yield iron and zinc contents. A few genotypes
showed higher micronutrient levels and seed yield along with lower phytic acid, suggesting their potential for breeding aimed at
enhancing micronutrient content and yield with low phytic acid levels in black gram.
