Agro-Morphological Characterisation of Exotic and Local Green Gram (Mung Bean) (Vigna Radiata) for Breeding Purposes in Uganda
Abstract

In order to start a good breeding programme that will potentially
develop high yielding and disease resistant varieties, germplasm
collection and characterisation is a prerequisite. The objectives
of this study were to characterise 38 local and exotic mung
bean genotypes with potential of being released as varieties or
being used for breeding purposes. The study also aimed at
determining the general and specific combining abilities for
crosses between local and exotic materials. This study was
done at Makerere University Agricultural Research Institute
Kabanyolo (MUARIK) and the National Semi-Arid Resources
Research Institute (NaSARRI). Results indicated significant
differences (P < 0.001) for nearly all traits in the two
experimental sites, indicating a high genetic diversity in the
genotypes studied. Genotype by environment interactions was
significant (P < 0.001) for all the traits indicating inconsistent
performance by some genotypes across the two locations. The
magnitudes of estimated broad sense heritability for the traits
used were generally high as the error and G x E variance
components were lower compared to genetic variance
component.
