Abstract
Bambara groundnut is an important underutilized crop rich in protein and comparable to cowpea and groundnut having nutritional benefits and also has certain constraints like presence of antinutritional factors which hinder its utilization. The present investigation was conducted to study the nature and magnitude of genetic variability and identification of protein rich genotypes with lower levels of antinutrional factors in bambara groudnut. Thirty genotypes were sown in kharif 2018 in experimental field plots of Genetics and Plant Breeding UAS, GKVK, Bengaluru. The genopypes were evaluated by following RCBD design with five replications and observations for ten quantitative traits were recorded. Analysis of variance revealed significant differences among all the genotypes. The estimates of genetic variability parameters and heritability coupled with genetic advance were higher for most of the characters. Grouping of genotypes into clusters using Tocher’s method resulted in the formation of 4 clusters. Thirteen out of thirty genotypes were selected for nutritional and antinutritional estimation. Analysis of variance for nutritional and antinutritional factors revealed significant differences among the genotypes. Protein content was highest for S-165A and lowest for SG-8. Antinutrients such as phenol content was lowest for SG-7 and highest for S-165A, phytic acid content was lowest for SG-8 and highest for DODRTZ, tannin content was lowest for SG-7 and highest for S-165A. The genotypes such as S-165A, uniswa red, SG-7 had high yield and high protein content. SB-42 derived mutant SG-7 had higher yield, higher protein and lower levels of phenol, phytic acid and tannin content.
