The present study was conducted with using split plot in a factorial design with three replications at agricultural and natural resources research center of lorestan province Iran from 2001 to 2003. The main factor was planting date with four levels started from 24 th of september Continued in a 10 days intervals and subplots were row spacing at two levels (18 and 36 cm) and there cultivars (SLM.046 , Regent×Cobra and Talaye). The analysis of variance was run and results showed that there werenot significant difference among planting dates. There were significant difference among cultivars for seed yield at the 5% level. Comparison among means indicated that Regent×Cobra cultivar was significantly higher (4685.5Kg/ha) than the two others (Talaye with 4063.4Kg/ha and SLM.046 with 3942.6 Kg/ha) and classified the former into a different class than the two later cultivars. Planting date × row spacing × cultivar intraction for seed yield , the number of seed in pod and pod in plant were significant on the 1% level. Year × cultivar intraction for seed yield characteristic was significant at the 1% level. Regent×Cobra cultivar with highest produtively is recommended for khoramabad conditions in Iran . Keywords : planting date , rapeseed cultivars , row spacing
