بررسی صفات کمی و کیفی لاینها و ارقام تریتیکاله در آزمایش مقایسه عملکرد مقدماتی یکنواخت

In this study 120 genotypes of Triticale that have been selected from international trials during the last cropping seasons, were evaluated in 2 different locations (Mashhad and Birjand) as yield trials. These genotypes were studied in preliminary yield trials, without replication, in comparison with the 2 check cultivars (Triticale: Juanillo 92, and Bread wheat: Marvedasht). Each line or cultivar was planted in a 7.2 m2 plot (6)(1.2 m2) and the final harvesting area was 6 m2 (5)(1.2). After each 20 lines 2 cheks replicated. The grain yield comparison among new lines and cultivars was cunducted at first with the curve shapeing and determination of potential yield stability was done using Ranking Method. After calculating of rank mean and standard division, 36 lines were selected for advanced yield trials in further season (ARTYT). The selected new lines had more grain yield in comparison to the check(s) cultivars and differed in their height, resistace to diseases, days to heading, days to maturity and shrowelling wich were more suitable than the checks.
