Assessing the variability based on nutritional, antinutritional parameters and ISSR markers among the promising genotypes of black gram (Vigna mungo L.)
Abstract
The present experiment “Assessing the variability based on nutritional and antinutritional parameters and ISSR Markers among the promising genotypes of black gram (Vigna mungo L.)” was carried out with a view to find out variability of promising genotypes on different nutritional and anti-nutritional components in a seed as well as molecular marker ISSR. Among the nutritional parameters, T-9 had the highest true protein content (26.88%), while GJU-2102 had the lowest (21%). The highest ash content was found in GU-2 (3.35%), and the lowest was found in GJU-2104 (2.16%). T-9 had the higher total sugar content of 5.38%. Results of present study showed that there is wide genetic variability among the genotypes of black gram despite being a self-pollinated crop. Molecular analysis revealed T-9 and GU-2 as the most diverse genotypes based on ISSR markers as well as dendrogram prepared from biochemical data, containing higher nutritional value and lower anti-nutritional value. These findings provide some information for selecting genotypes with desirable nutritional traits and molecular diversity.
