Evaluation of advanced oilseed rape lines response in on-farm condition of Mazandaran

In order to evaluation of adaptability of rapeseed promising line, 9 lines along with check, totally 10 genotypes: G1, G2, G3, G4, G5, G6, G7, G8, G9 and G10 were evaluated based on randomized complete block design with three replications in Behshar and Dashtenaz-Sari on farm condition during 2012-13 cropping seasons. The results of combined analysis of variance revealed that the genotypes had significant difference for days to flowering, days to end of flowering, duration of flowering, days to maturity, plant height, pods per plant and seed yield. All the traits except duration of flowering were significantly affected by environments. The average seed yield of the genotypes in Behshar and Dashtenaz were 1652.9 and 2505.7 kg ha^-1, respectively which were classified in two separate statistical groups. The genotypes maintaing G2, G7, G6 and G9 with 204, 205, 207 and 207 days to maturity were considered as early maturing genotypes. The genotypes including G2, G1, G8 and G10 with average seed yield of 2501.1, 2265.6, 2415.5 and 2406.6 kg ha^-1, respectively for two environments were considered as superior genotypes.
