The performance of 44 elite mungbean genotypes for nine quantitative traits under three
heterogeneous environments was evaluated for genotype×environment interactions and stability parameters.
The genotype×environment interaction was significant for 1000-seed weight, number of seeds/pod and days
to 50% flowering. In all 22 genotypes exhibited stability across the environments with regard to one or more
morphological characters. Water stress during early stages of development to flowering stage and/or from pod
development to harvest during 2009 and 2011 resulted in the lower seed yields. Contrary to this, during 2010
continuous rains coupled with high relative humidity and comparatively the lower temperatures during the
cropping season resulted in higher seed yields. Despite of the fact that 18 genotypes were recorded with higher
seed yields, of which only four genotypes MH-521, GM-9924, ML-1333 and Ganga-8 exhibited stability across
environments indicating their adoption to arid and semi-arid regions.
