Due to some positive effects in rotation with wheat cultivation of rapeseed was successful in warm drylands of Iran. The present study carried out to comparison new rapeseed double zero varieties with hybrid check. Experiment conducted in RCBD with 3 replications and 2 locations (Sarpol-e-zahab and Gachsaran) with 10 new spring varieties alongwith 2 checks i.e. Hyola401 and Sarigol. Each variety/hybrid planted in 5 rows with 4 m length plots before the first effective rain. During growth season in addition to weeding, spray against pests and diseases some agronomic characters noted. Seed and oil yield calculated and oil content measured by NMR after harvesting. Results of combined analysis showed significant difference among genotypes for seed and oil yield which was due to significant differences in seed weight and number of seeds per pod. Mean comparison showed that seed yield rang was 161.8 to 981.7 Kg/ha, and oil yield was 71.2 to 457.2 Kg/ha that belong to Hysun110 and RGAS0324, respectively. Hyola401 seed and oil yield was the highest after RGAS0324. Rank analysis showed that Hyola401 had the best rank with zero standard deviation and high seed and oil yield in both locations. RGAS0324 was the best variety which had the closed seed and oil yield to Hyola401 and had good adaptability to sarpol-e-zhab area.
