AMMI Analysis for Green Pod Yield Stability of Snap Bean (Phaseolus vulgaris L.) Genotypes Evaluated in East Shewa Zone, Oromia, Ethiopia

The experiment was conducted at Adami Tulu Agricultural Research Center (ATARC), Lume and Dugda Districts during the 2019 2020 main cropping seasons to identify adaptable high yielder snap bean genotypes for East Shewa Zone similar agro ecologies. Ten were used as planting material. laid down in Randomized Complete Block Design (RCBD) with three replications. AMMI model shows that environment accounted 40.93%, GXE 31.79%, genotype 12.70% of total variation. percentage indicates major factor influencing yield performance beans is environment. first two IPCAs are most accurate could predict genotype’s stability explained by IPCA-I (53.10%) IPCA-II (21.1%) GEI. This result revealed there differential performances among across testing environments due presence According parameters (ASV, GGE Biplot) mean results G-24 G-12 stable test locations. Therefore, proposed candidate possible release.
