In order to investigate the adaptation of different cultivars and hybrids of sunflower to Zabol climate, an experiment was carried out in 1380-81 on Research Farm of Zabol. In this experiment 11 genotypes of sunflower including 9 hybrids and 2 cultivars were compared by RCBD with 4 replications. Genotype differences was significant at 1% level of planting time to flowering, time from planting to maturity, 1000-seed weight, and seed yield. Genotype differences were significant at 5% of time from flowering to maturity, plant height, number of leaves per plant, and number of seeds per capitol. The most period of growing from planting to flowering with 87.5 days, from flowering to maturity with 39.25 days, and from planting to maturity with 127.75 days was belonged to Record cultivar, and at least period of growing from planting to flowering with 71.25 days, and from planting to maturity withl08 days was belonged to the hybrid of CMS31* R-94. Also, at least period of growing from flowering to maturity with 35.75 days was belonged to the hybrid of CMS24*R-8111. Record cultivar had maximum plant height, number of leaves per plant, capitol diameter, and number of seeds per capitol, and Chernianca cultivar had maximum of 1000-seed weight and seed yield. The minimum plant height, number of leaves per plant, capitol diameter, and number of seeds per capitol, 1000-seed weight, and seed yield per hectare were belonged to hybrids of CMS31*R-94, CMS31*R-94, CMS24*R-81/1, CMS24*R-14, CMS60I52*R-92 and CMS 24*R-81/1.
