Resumo: | Analyses of genotype by environment interactions were carried out for wheat genotypes grown under irrigated and non-irrigated field conditions, in two sowing dates during three years. The linear regression method was used to analyze the stability of grain yield. Genotype by environment interactions was observed for grain yield in all groups of environments. Nesser was the most productive and stable genotype in all groups of environments, followed by IAPAR 17-Caeté. In the late sowing, better yield performances were observed for the cultivars OCEPAR 7-Batuíra, IAPAR 17-Caeté and Nesser, under irrigated condition, and Nesser and IAPAR 28-Igapó, under non-irrigated condition. The results indicated that Nesser gave high grain yield with superior adaptability and stability, and could thus be considered as the most suitable genotype for late sowing and water stress condition at the end of plant cycle. |
