Abstract

In order to determine the best cultivars and planting date of oilseed rape, an experiment was carried out in two years (2000-2002) at Agricultural Research Station of Haji Abad. The experiment was a split plot design on randomized complete block basis with four replications. The main plots included four planting date (22 Oct. 31 Oct., 10 Nov. and 20 Nov.), and the sub plots included three cultivars Sarigol, Hyola 401 and Option 501). The results of combined analysis showed that effects of year, planting date, cultivar and interaction between them were significant on number of days from emergence to flowering, duration of flowering and physiological maturity at the 1% level. Cultivar Hyola 401 had the lowest and Sarigol had the highest number of days from emergence to fowering and physilogical maturity. Hyola 401 had the highest and Sarigol had the lowest duration of flowering. In planting date treatment, all characters decreased with delay in planting. The effect of cultivar was significant on number of pods per plant and 1000 seed weight at the 1% level, and Hyola 401 hybrid had the highest 1000 seed weight. The effects year ad cultivar was significant on seed weight at the 1% level. Hyola 401 hybrid produced the highest seed yield (2597 kgha-1 ( .
