Abstract

Fifteen foliar disease resistant groundnut genotypes and one local variety (VRI 4) were evaluated over four seasons in a single location to identify the stable high yielding genotypes. Significant G X E interaction showed the differential performance of genotypes over different environments / seasons. Stability analysis revealed that only one genotype (ICGV 92093) had near unity regression coefficient coupled with non-significant deviation from regression and high mean kernel yield. Hence, the genotype may be recommended over wide range of environments / seasons.
