Abstract
Ten promising genotypes of groundnut were evaluated for their adaptiveness and stability performance at eight different locations during 1997. The G x E interaction was highly significant. The regression coefficients (b) ranged from 0.76 to 1.17 and deviations from regression (S2d) ranged from 0.06 to 0.82. BM-28 and ICGV-86550 showed above average performance, unit slop and non significant deviation from regression and thus are suitable for wide range of environments. Four genotypes, Gori, ICG-7326, CINA and Chinese 68-4 possessed b < 1 and mean performance was also below average hence are suitable for poor environment. Out of all the tested genotypes, ICG-4993 had greater than unit regression coefficient (bi=1.14) and highest significant (S2d) (0.82) indicating its unsuitability for wider cultivation.
