بررسی خصوصیات زارعی و عملکرد دانه لاینهای جو در آزمایشات مقدماتی مشترک در مناطق سردسیر دیم

In order to evaluation of selected lines from 1386-87 observational and internal preliminary yield trials , this researchwas carried out in Maragheh , Gamloo, Zanjan and Shirvan stations. For study lines in various climatic conditions of these stations, experiment had 27 same lines that were planted non-replicated.Check was replicated after each 9 lines. During growing season observations were recorded on sowing date, date of emergence, cold damage, diseases infection,days to heading,plant height and days to maturity. After harvesting , grain yield and 1000 kernel weight was measured . Finally based on compairing yield of lines with near check and according to desirable traits such as ealy maturity, cold resistance and suitable plant height, 9 lines were selected. Selected lines completely will be studied in next regional advanced yield trials in cold region stations.
