Genotype by year interaction for selected quantitative traits in hybrid lines of Triticum aestivum L. with Aegilops kotschyi Boiss. and Ae. variabilis Eig. using the additive main effects and multiplicative interaction model

Abstract This study estimated the genotype × environment interactions for ten yield associated traits in advanced generation hybrids of several cultivars common wheat ( Triticum aestivum L.) with Aegilops kotschyi Boiss. and A. variabilis Eig. using additive main effects multiplicative interaction (AMMI) models. Tests were ran over five years at one location replicated field trials. The AMMI model showed significant genotypic environmental all analysed traits. A majority hybrid lines less stable than their parental wheats. older cultivars, lower sensitivity, most stable. best total selection index, combined, was observed oldest cvs. Gama Rusa?ka, among lines, Ae. /Rusa?ka//Smuga /Rusa?ka//Muza. /Rusa?ka//Smuga, /Rusa?ka//Muza, /Rusa?ka//Korweta, /Rusa?ka//Begra///Smuga, /Rusa?ka//Begra///Turnia are recommended inclusion breeding programmes due to greater stability good average values
