Genotype, Environment, and GXE Interaction Effect on Some Selected Traits of Taro (<i>Colocasia esculenta</i> (L.) Schott)

The experiment was conducted to evaluate the nature and extent of genotype environment interactions, select stable high yielding taro genotypes for fresh storage corm yield, related traits identify most representative discriminating in southwest Ethiopian regions. study tested across four environments (Jimma, Agaro, Gera, Metu) two cropping seasons Ethiopia. Nine selected promising one standard check (Denu) were evaluated by using RCBD that replicated three times. important data collected from all location analyzed different statistical software’s. result showed significant differences (p<0.01) genotype, environment, interactions (GEI) effects exceptions root length. It also revealed mean square more than those GEI targeted indicated uniqueness test environment. 053 133 identified as an ideal being yield wider adaptability hence nominated release then production. GGE bi-plot Agaro-2 Gera-2 their useable traits. Four mega-environments (MGE) breeding; where Agaro-22, Gera-2, Gera-1 combined into MGE-1, Metu-1, Jimma-1 fell a separate MGE-2, Jimma-2 Agaro-1 pooled MGE-3, Metu-2 separated MGE-4, respectively.
