تجزیه پایداری عملکرد دانه لاینهای اینبرد نوترکیب گندم نان.

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: The results of analysis of simple and compound variances showed a significant difference between the lines in terms of grain yield. Comparing the average of all the lines, lines No. 3, 12, 38, 42, 47, 95 and Roshan had the highest yield and the lowest average seed yield was related to line 51 with 3.023 tons per hectare. Line 90 showed good general compatibility compared to other lines. Lines No. 3, 38, 42, 95, their regression coefficient was less than one and the deviation from their regression line was higher. One of the practical aspects of this research is the identification of promising lines for carrying out further breeding studies in order to release the variety and introduce it to farmers. 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.
