Stability assessment for selection of elite sugarcane clones across multi-environment based on AMMI and GGE-biplot models

Abstract Seven field experiments were conducted at three experiment stations representing major sugarcane producing regions in Egypt. Each comprised a randomized complete block design with replications. Fourteen elite breeding lines typical of those routinely generated the final selection stages programs Egypt, along one check variety (GT54-9) evaluated for cane and sugar yield this study during 2018/2019, 2019/2020 2020/2021 seasons. Stability parameters including cultivar stability rank superiority index determined. The data was also investigated using GGE-biplots, additive main effects multiplicative interaction model (AMMI), AMMI value (ASV). genotype effect used to visualize G x E interaction. results these trials are significance guiding recommendation superior varieties more stable production zones. clone G.2016–129 had mean exceeding that GT54-9, hence recommended commercial planting. Because local conditions an would have high adapt wide range environments. In present study, only fit definition by higher than GT 54–9.. At side multivariate analyses, ASV (AMMI value) supports Method. Varieties lowest stable. Therefore, exposed G.2016–95, F-150 contrast, G.2009–11, G.2016–128, G.2016–95 yield, clones yields, respectively.
