stability: Genotype-by-Environment Interaction and Yield Stability Analysis

Analyses multi-environment trials of plant breeding, laid out in randomized complete blocks in every environment, to find genotypes that are high-yielding and stable: analyses of variance in each environment and combined; Eberhart and Russell's analysis (1966) <doi:10.2135/cropsci1966.0011183X000600010011x> and Finlay and Wilkinson's regression (1963) <doi:10.1071/AR9630742>; Wricke's ecovalence, Shukla's stability variance (1972) <doi:10.1038/hdy.1972.87> and Kang and Pham's yield-stability statistic (1991) <doi:10.2134/agronj1991.00021962008300010037x>; Kang's rank-sum and Fox's top-third ranking; Eskridge's safety-first indices (1990), Annicchiarico's reliability index (1992), Lin and Binns' superiority measure (1988) and Huehn's nonparametric statistics (1979) with tests; additive main effects and multiplicative interaction (AMMI) analysis with biplots and AMMI stability values on any number of axes; the GGE biplot with which-won-where, mean-stability and discrimination views in three scalings; and a plain-language interpretation of every result, computed from its numbers.
