Development of rapeseed internal hhybrids is effective way for reduction of relation to importing rapeseed seeds. In order to development of superior rapeseed genotypes which comprising the ideotype traits such as early maturity, resistance to lodging and diseaes and high seed yield and adapted to Caspian seashore condition, 15 hybrids along with local checks including Hyola401, RGS003, Line41, Zafar, totally 20 genotypes were evaluated based randomized complete block design (RCBD) at Agriculture Research Station of Baykola in 2013. F1 hybrids were produced with the crossing of restorer lines including R1, R2, R4 and R8 with A lines of RGS003, RGS3006, Sarigol, 22BH and RW008911. In this study, the hybrids including 5/003/R1, 5/22/8-9 and G/3006/R4-1 had 3256.6, 3128.8 and 3078.8 kg ha-1 , respectively were superior genotypes and they were classifed with Zafar with seed yield of 3073 kg ha-1 in the same statistical group. The resulted hybrids had some percentages maile sterility, therefore the restorer lines should be more researched.These genotypes had 115.3, 100.3 and 105 days to floweing and also 210.3, 208.7 and 208.7 days to maturity, respectively. Key words: check varities ,rapeseed, internal hybrids and seed yield.
