عملکرد یک ژنوتیپ ممکن است از مکانی به مکان دیگر و یا از سالی به سال دیگر تغییر یابد و در اصطلاح اثر متقابل ژنوتیپ×محیط وجود داشته باشد. برای به­نژادگران مطالعه اثر متقابل ژنوتیپ×محیط و شناسایی ارقام پایدار و با عملکرد بالا از اهمیت زیادی برخوردار است. در این تحقیق، پایداری و سازگاری 20 ژنوتیپ جو در آزمایش­های یکنواخت سراسری با استفاده از طرح بلوک­های کامل تصادفی با سه تکرار در 8 اقلیم سرد به مد...

One of the most complicated issues in plant breeding programs is genotype by environment interaction. To evaluate seed yield stability of 18 chickpea promising lines, a field experiment was conducted using randomized complete block design with four replications in two cropping seasons (2018-19 and 2019-2020) in four research stations (Maragheh, Kurdistan West Azerbaijan and Hamedan), Iran. Comb...

In order to determine yield stability of 20 durum wheat genotypes, a trial was carried as randomized complete block design with four replications in four years during  2009- 2014 in Sarab-Changae station of Khorramabad, Iran. Analysis of combine variance showed that environment, genotype and genotype × environment interaction were significant at 1% probability level. Variance analysis of additi...

Assessment of the stability and adaptability of a genotype to different environments is useful for recommending cultivars for known conditions and is one of the requirements in plant breeding programs. Considering the inherent climatic diversity in Iran, recognition of genotype by environment interaction is important. In this study ten oat (Avena sativa L.) genotypes were tested at six environm...
