    Abstract: Genotype by environment interactions are studied to gain a better understanding of various phenomena. Among which yield stability can be highly determined by evaluating genotypes across different testing sites. This study was conducted to determine the effect of genotype × environment interaction (GEI) on grain yield, and to asses yield stability o... Show More
