Sixty four accessions of black gram genotypes which
included 61 germplasm accessions and three released check
varieties were studied over four environments of rainy and
post rainy seasons of 2008 and 2009 for their seed yield and
stability.The results have shown that KARS-112 and KARS-
170 with bi < 1, performed better in sub-optimum
environments while CN-9078 and KARS-269 with bi > 1,
performed well in optimum environments. However, five
accessions viz., PSR-3798, KARS-235, KARS-012, SKN-138
and KDRS-251 with bi = 1, demonstrated better yield per
plant in both optimum and sub-optimum environments
(four seasons) and also outperformed the best check PU-
19. The study thus shows that genotypes KARS-112 and
KARS-170 are better suited for sub-optimum environments
like drought prone areas and CN-9078 and KARS-269 are
more suited for high input, favourable environmental
regions of coastal ecosystems along with areas of assured
rainfall, fertilizer and other inputs. However, PSR-3798 and
KARS-235 R the most stable with wider adaptability to both
poor and better environment
