بررسی خصوصیات زراعی و عملکرد دانه ژنوتیپ های جو در آزمایش های مقایسه عملکرد بین المللی مناطق سردسیر دیم

In order to evaluate the international material in different climatically conditions, in coordinate with international center for agricultural research in the dry areas (ICARDA), a number of 251 barley genotypes within 3 international nurseries named IBON-W-09, IBCB-W-09 and IBYT-W-09, were evaluated in 4 Ghamloo, Maragheh, shirvan and zanjan dryland and cold research stations. All experiments were designed and planted based on suggested layouts. Considering different climatically conditions Seed rate was differs from 400 to 450 grain per square meter. During growing season notes were taken on days to heading, days to maturity, plant height, lodging, disease, pests and yield. Finally based on all agronomic trials and yield production a number of 32 superior genotypes form IBON, 42 genotypes from IBCB and 11 genotypes from IBYT materials were selected. For more evaluation, selected genotyps conducted to internal reginal preliminary yield trial in cold stations, 2010-11 programs.
