In order to study of reaction of commercial rapeseed cultivars to delayed sowing time under water deficit conditions, an experimental was carried out in a factorial split plot design based on RCBD with four replications for two years. Treatments were included: 1- Planting date in two levels as main plots such as common planting date and delayed sowing time. 1- Irrigation in two levels as main plots such as common irrigation and no irrigation from flowering to end of growth. 2- Varieties as sub plots including of Okapi, Zarfam, Orient, Talayeh, SLM046, Licord, Opera, Modena , RGS003 and Sarigol. The results showed that simple effects of planting date, irrigation and variety and also interaction effects on seed yield were significant at 1% level probability. RGS003 (5341 kg/ha) in planting date and common irrigation had the highest seed yield. Simple correlation among characters showed that seed yield with pod per plant, seed per pod, 1000 seed weight, oil percent and oil yield had significant correlation at 1% level probability.
