Abstract: 

In order to evaluation affect of different planting dates on quantity and quality characteristics and grain yield in spring cultivars of canola (Brassica napus L.), an experiment was carried out at split plot based on RCBD with three replications at Chaloos region in 2010. Main factor were selected planting dates (4 and 19 February, 5 March and 20 April) and sub factor was canola cultivars including Hayola 401, Sarigol, RGS003 and Zarfam. Results showed with delay in planting date, phonological traits including vegetative period long, flowering period long and growth period long were decreased. The maximum of grain yield (2325 kg.ha-1) were obtained in 4 February, because the most of the pod length, pod number per plant and seed number per pod due this treatment. Delay in planting date to cause of decreased significant different on quantity and quality characteristics and due to decreased grain yield. Hayola 401 and Sarigol cultivar had been the most grain yield (2136 and 2086 kh.ha-1), and RGS003 and Zarfam cultivars had been the least grain yield (1972 and 1904 kg.ha-1). The least of oil yield were obtained in 20 April and the most of oil yield were produced in 4 and 19 February. Hayola and Sarigol cultivars had been the most of oil yield and RGS003 and Zarfam cultivars had been the least of oil yield. Non significant between planting dates × cultivars for investigated characteristics were indicated traits in cultivars, all of traits had been same change due to in different planting dates. Therefore, planting date of 4 February due to as most of grain yield introduced the best of treatment.
