بررسی صفات کمی و کیفی ارقام و لاین های گندم دوروم در آزمایشات مقایسه عملکرد یکنواخت مقدماتی ‭(PRDWYT-M) ‬اقلیم معتدل کشور

To obtain high yielding durum wheat lines with desirable grain quality and resistant to diseases, 123 durum genotypes originated from 2003-2004 international durum wheat nurseries were tested in 4 locations in temperate regions ofIran(Karaj,Neisbabour ,Varamin and Gonbad). The experiments were conducted without replication and the checks were planted after each 10 genotype intervally. Each plot included 6 rows with row spacing of about 20 cm. During the season the occurance ofphenological stages, plant height, lodging, response to diseases and after harvesting the yield and grain color of genotypes were recorded. Using Rank and SDR methods, 34 genotypes were selected for advanced durum . wheat yield trials (ADYT) for next crop season.
