Abstract
Background & Objective: Investigating the stability and compatibility of a genotype in different environmental conditions in order to introduce it for planting in specific and known environmental conditions in multi-breeding programs is one of the basic needs and to achieve sustainable production in order to achieve sustainable self-sufficiency in It is necessary to produce strategic products, especially wheat.
Methods & Materials: In the present study, in order to investigate the stability and identify high-yielding and compatible genotypes, the yield of 32 lines of recombinant inbred from the crossing of two cultivars Roshan and Superhead in the form of a randomized complete block design with three replications in six The region (Tabriz, Ahar, Ardabil, Faghan, Shabestar and Urmia) were investigated for two years.
Results: The results of the present study showed that there was a significant difference between the locations in terms of performance. Also, the difference between genotypes, as well as the interaction effect of genotype × year, genotype × location, and the interaction effect of genotype × year × location were significant, which indicated the difference between the performance of genotypes in different environments, which indicated the necessity of stability analysis.
Conclusion: According to the relative alignment of the results obtained from different methods, it can be stated that in this research, lines 10, 12, 31 and the Roshan variety were recognized as the most stable genotypes and line 51 as the most unstable line and It was recognized as special for unfavorable areas.
