بررسی ارزیابی عملکرد و پایداری ژنوتیپ های گندم نان زمستانه در آزمایش مقایسه عملکرد پیشرفته اقلیم سرد کشور ‭(ARWYT-C)‬

This study was conducted to select high yield promising bread wheat lines tolerant to diseas~s and cold with higher adaptation. In this study 36 pure lines selected from a . preliminary yield trial, PRWYT (1383-8J , and 18 lines from Hungary were studied in three separate experiments (RCBD) with three replications at seven research stations of cold zone. The results of combined analysis showed that the lines were significantly different in grain yield. Also location and location x genotype effects were significant, so stability of the advanced lines were tested using Rank method Based on the results of analyses of variance and stability, desirable agronomic traits, bread quality and resistance to important wheat diseases of cold area, I ~romising lines were selected. These lines will be studied in ERWYT-C trial in two consecutive next using which new cultivares are likely to be released.
