بررسی عملکرد دانه لاین‌های زمستانه کلزا

In order to Study and investigate the preliminary yield comparison of oilseed rape lines, 15 lines along with check cultivars SLM046, Licord, Zarfam, Opera, Modena and Okapi were evaluated in Karaj, Kermanshah, Hamadan and Mashhad in 2011-2012 cropping seasons using randomized complete block design with three replications. During the farming season all agronomic traits such as days to start flowering, end of flowering, plant height, number of seeds per pod, number of pods on main stem, number of branches, total pods per plant, maturity were recorded. Based on the results of the four sites of experiment lines number 8 (BAL-8), 9 (BAL-9), 15 (BAL-15), 1 (BAL-15), 3 (BAL-3), 7 (BAL-7), 11 (BAL-11), 6 (BAL-6) and 2 (BAL-2) with 4116, 3748, 3744, 3718, 3686, 3528, 3427, 3413 and 3402 kg/ha seed yield respectively were superior than or equal to check variety Okapi which ranked 8 with 3511 kg/ha seed yield. Selected lines with high yield and suitable traits will be evaluated in advanced yield triales in cold and mild cold regions in two years.
