گزارش نهایی طرح تحقیقات ارزیابی لاینها و ارقام گندم های نان زمستانه و بینابین در آزمایش یکنواخت مقدماتی مقایسه عملکرد دانه در اقلیم سرد کشور‭(PRWYT- C)‬

Achievement of wheat cultivars with high and stable yield and appropriate agronomic traits like resistance to diseases, are the main objectives in breeding programs. This study was conducted to select bread wheat lines with high yield, appropriate traits, resistance to diseases and wide adaptation using 220 lines in systematic design at 8 cold regions in 2001/02 cropping season. Comparison of genotypes and determination of their stability was carried out using non-parametric statistic method (rank). Based on results 36 genotypes were superior than or equal to the check cultivars and selected to evaluate further in advanced yield trial of ARWYT in 2002/03 cropping season. Key words: Rank method, grain yield, advanced yield trial of ARWYT, resistance to diseases, stability
