To evaluate the phenotypic diversity, yield potential, and genetic variability of a large panel of soybean genotypes under the agro-ecological conditions of the Madhupur Tract in Bangladesh.
Evaluated 278 soybean genotypes in a randomized complete block design with two replications in Bangladesh from November 2023 to April 2024.
Recorded morphological, phenological, physiological, and yield traits and evaluated them using analysis of variance, correlation analysis, principal component analysis (PCA), and genetic parameter estimation.
Grain yield per plant ranged from 0.46 to 20.06 g, with BS-53 producing the highest yield and BS-260 maturing earliest at 88 days.
Grain yield per plant correlated strongly and positively with seeds per plant (r = 0.906, p < 0.001) and pods per plant (r = 0.862, p < 0.001), while the first two principal components captured 67.4% of total phenotypic variation.
Most evaluated traits exhibited high broad-sense heritability alongside high genetic advance, indicating strong responsiveness to selective breeding.
