Abstract

Zafar as a new rapeseed cultivar is the cross which was made between 19H and Sarigol line/cultivar in 2003. The pedigree selection was applied to mange the segregating generations. The results of evaluation made during 2008-09 and 2009-10 showed that Zafar with an average seed yield of 3810 kg ha-1 was among superior genotypes identified. Further evaluation on these genotypes as a mid-maturity/spring type rapeseed lines was made under on-farm conditions in mid-lands/highlands of Mazandaran province. The results revealed that Zafar with an average seed yield of 2595 kg ha-1 was superior as compared to Sarigol as the local check cultivar. The results obtained from the experiments conducted under on-farm conditions of mid-lands of Mazandaran province in two locations demonstrated an average 800 kg ha-1 superiority of Zafar cultivar to the check, Sarigol. Additionally, Tolerance to sclerotinia root of Zafar was similar to the reactions of the local check varieties. This variety is considered suitable for cultivation in mid-land of Mazandaran province and similar climatic regions.
