“…Subsequently, referring to result of Bartlett's test, combined analysis of variance was done (Crossa, 1990). Stability statistics including coefficient of variation (Franscis & Kannenberg, 1978), Wricke's ecovalance (Wricke, 1962), Shukla stability variance (Shukla, 1972), regression line slop (Finlay & Wilkinson, 1963), genotypic stability (Hanson, 1970), Plaisted stability parameter (1960), mean square of GEI (Lin & Binns, 1988), priority index (Lin & Binns, 1988), and Tai's alpha and lambda (1971) were performed for each genotype. Rank-sum method (Kang, 1988), as one non-parametric statistic was measured for experimental genotypes.…”

“…Becker and Léon (1988) suggested that ecovalance (Wricke, 1962) and stability variance (Shukla, 1972) give same results for ranking of genotypes. Hanson (1970) has proposed a genotypic stability (D i 2 ), which based on this statistic genotypes V3, V5, and V1 were most stable. Considering regression procedure of Tai (1971), the highest stability was obtained by genotypes V6, V9 and V12 ( Figure 1).…”

Different methods have been developed to estimate of genotype by environment interaction (GEI) in crop plants. In this study, 14 kabuli type chickpea genotypes were assessed for seed yield in four stations over three successive years (2010)(2011)(2012)(2013) at west highlands of Iran. Randomized complete block design was used in all test environments with four replicates. Combined analysis of variance for seed yield revealed significant differences between genotypes, locations, and interaction between these two sources. The mean seed yield of genotypes averaged over environments showed that V4 and V2 had the highest (1163.58 kg ha -1 ) and the lowest seed yield (759.07 kg ha -1 ), respectively. Significant GE interaction implied that chickpea genotypes had various responses to different environments and, the stability analysis could be performed. To investigate GEI and identify the best performing stable genotypes, several stability parameters were employed. According to Wricke's ecovalance, stability variance, Plaisted method, and genotypic stability V5, V8 and V3 were the most stable genotypes. Based on CV, regression coefficient and MS(GE), V1 and V5 found to be stable and adapted to diverse environments, and the other genotypes distributed among stability statistics. Based on the AMMI biplot, 12 test environments divided into two mega environments. These mega environments included very cold districts like Maragheh and similar areas, and relatively softened regions of Kurdistan and similar environments. For these two mega environments, V6 and V4 showed more adaptability, respectively. In conclusion, the two genotypes, V4 (FLIP 00-39C) and V6 (FLIP 99-26C) could be recommended as new cultivars to chickpea farmers for autumn sowing in west areas of Iran.

“…Hanson's (1970) genotypic stability (D 2 ) is founded on regression analysis since it uses the minimum slope from the Finlay and Wilkinson (1963) method. Freeman and Perkins (1971) suggested the use of an independent measure like one replicate to determine the environment index and the remainder of replicates being used to determine genotype means.…”

Lentil (Lens culinaris Medik.) is traditionally grown as a rain fed crop, particularly in the Middle East; its seed is a rich source of protein for human consumption in developing countries such as Iran and others. The stability of 11 different lentil genotypes was investigated using 19 univariate stability parameters. Field experiments were conducted in 20 rain-fed environments in Iran's lentil producing areas to characterize genotype by environment (GE) interactions on seed yield of 11 lentil genotypes. Combined analysis of variance across environments indicated that both environment and GE interactions significantly influenced genotype yield. Several statistical methods and techniques were used to describe the GE interaction and to define stable genotypes in relation to their yield. The results of these different stability methods were variable. However, most showed genotype FLIP 92-12L was stable and genotype Gachsaran was unstable. Genotypes identified as superior differed significantly from local cultivars and can be recommended for use by farmers in semi-arid areas of Iran. Principal component analysis was used to obtain an understanding of relationships among stability techniques. It showed the parameters studied could be grouped in five distinct classes. Clustering of the genotypes indicated that there were two genotypic groups in this group of genotypes.Additional key words: adaptation, multi-environmental trials, regression analysis, variance component. ResumenInteracción genotipo × × ambiente de la producción de grano de genotipos de lenteja y su relación con técnicas estadísticas de estabilidad univariadas La lenteja (Lens culinaris Medik.) se cultiva tradicionalmente en regadío, particularmente en el Oriente Medio, y su semilla es una fuente rica de proteínas para consumo humano en países en desarrollo como Irán y otros muchos. Se investigó la estabilidad de 11 diferentes genotipos de lenteja utilizando 19 parámetros univariados. Para caracterizar la interacción genotipo × ambiente (GE) de la producción de grano de 11 genotipos de lenteja, se realizaron experimentos de campo en 20 ambientes de regadío de las áreas productoras de Irán. Análisis combinados de varianza entre ambientes indicaron que tanto los ambientes como las interacciones GE influyeron significativamente en la producción de los genotipos. Se utilizaron varios métodos estadísticos para describir la interacción GE y definir los genotipos estables respecto a la producción. Los resultados de los diferentes métodos fueron variables, pero la mayoría mostraron que el genotipo FLIP 92-12L es estable y que Gachsaran es inestable. Los genotipos calificados como superiores difirieron significativamente de los cultivares locales y pueden ser recomendados para ser utilizados por los agricultores de las zonas semi-áridas de Irán. Se utilizó un análisis de componentes principales para analizar las relaciones entre las técnicas de estabilidad. El análisis mostró que los parámetros estudiados pueden ser agrupados en cinco clases, y los genot...

“…Several methods and techniques have been developed to describe and interpret the response of genotypes to variation in the environment. Biologically, genotype with minimum total variance under different environments is considered stable (Hanson, 1970). An agronomically stable genotype has a minimum interaction with environments but responds favourably to improving environments (Eberhart et al, 1966).…”

The main objectives of this investigation is to determine the GEl effects on grain yield of superior BILs derived from Swarna × WAB 450 inter cross and to select genotypes that are widely adapted across upland rice growing rainfed areas in North Karnataka, India. Multi-location yield trials of nineteen superior BILs (BC1F8) and three checks selected for earliness, productivity, reaction to blast diseases and grain size were conducted at three locations in six environments. Result of Additive Main effect and multiplicative interaction (AMMI) analysis showed that genotypes, environments and GEI components were significant. Out of twenty two genotypes evaluated for GEI effect in this study, six genotypes were found suitable for all environments; six genotypes for favourable environments while ten genotypes were identified as suitable for unfavorable environments.
