Deskripsi
Fifteen foliar disease resistant groundnut genotypes and one local variety (VRI 4) were evaluated over four seasons in asingle location to identify the stable high yielding genotypes. Significant G X E interaction showed the differentialperformance 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 highmean kernel yield. Hence, the genotype may be recommended over wide range of environments / seasons.
