Abstract

The nutrient-dense Bambara groundnut is renowned for its ability to withstand extreme weather conditions. Its use is still restricted despite its potential because of problems such a hard seed coat, prolonged cooking times, and poor germination. In this study, a group of landraces from all over Africa was evaluated for genetic diversity in important seed-associated properties. Using a completely randomized approach with three replications, 60 genotypes were assessed for seed hardness, germination performance, and seedling vigor. R version 4.1.1 was used to analyze the data from the experiment, which was carried out at Jimma University College of Agriculture and Veterinary Medicine in Ethiopia. Each trait's broad-sense heritability and genetic and phenotypic coefficients of variation were calculated. For every evaluated attribute, the analysis of variance showed highly significant differences (p<0.001) between genotypes. Except mean germination time, every attribute showed significant heritability and genetic advancement, indicating limited environmental effect and strong additive genetic control. As a result, these qualities present excellent targets for breeding program selection. Interdependence between attributes was demonstrated by the positive and significant association between hundred-seed weight and seed length, width, thickness, electrical conductivity, and compression force, as determined by Pearson correlation analysis. These findings lay the groundwork for direct trait selection to increase seedling establishment and cooking quality in Bambara groundnuts.
