Abstract: Some mung bean genotypes were evaluated to estimate the level of genetic variability and identify traits that are closely linked to seed yield. The evaluation was conducted at three locations in 2022 and 2023. The experimental design was randomized complete block (RCBD) replicated three times. Parameters measured included flowering, pod and other yield parameters. Data were analyzed using SAS. Most of the parameters measured had significant mean squares of genotypes and high broad-sense heritability. Estimates of genotypic variance were significant and larger than environmental variance estimates for most of the parameters. Expected gains ranged from low (1.46%) in pod weight/plot, to high (23.49%) in pod length. Strong positive phenotypic and genotypic correlation existed between pod and seed weight per plot, and seeds per plot, as well as pod length. The study revealed substantial variability in the mung bean genotypes and presented number of seeds per plot and pod length as major components of mung bean grain yield. Progress will be made in the improvement of the crop for grain yield.
