Abstract

Analysis of genetic diversity in wild and cultivated plants is an essential requirement for any crop improvement involving genetic engineering, which includes evolution, ecological, geographical, and human factors, particularly in underutilized crops like Bambara groundnut. Therefore, knowledge of the genetic factors responsible for this character's inheritance is important for initiatives involving breeding that present significant genetic diversity in collections of germplasm. Five Bambara groundnut genotypes were evaluated using randomized complete block design with three replications. Three categories large, medium, and small seed sizes were used to group the seeds.  For the majority of vegetative variables in the current study, significant differences were found across all 5 genotypes, 15 combinations of seed size and genotypes, seed size categories, and the interaction between genotype and seed size categories. For the overall variable, the impact of the environment on these traits was demonstrated by the fact that the phenotypic coefficient of variation was greater than the genotypic coefficient of variation. Moreover, low heritability and genetic advance were observed for whole vegetative traits. Both the phenotypic and genotypic coefficients of variation (GCV and PCV) estimation ranged from (0 to 10.71% and 3.84 to 48.36% respectively, for the vegetative parameters. Moderately GCV amounts (10.71%) and high PCV (24.77%) was recorded for the number of branches for each plant and the number of days to emergency. GCV (10.40%) and PCV (29.69%), while low GCV and high PCV have been recorded from rest vegetative variables except days to maturity that was low for both GCV and PCV. Further studies should be carryout for seeds weight on vegetative traits for improvement of these Bambara genotypes under different environments.
