New idioplasmic resource B. napus L. with multi-loculus founded by interspecific hybridization
Multi-loculus B. juncea L. (more than three loculus pod separated by septa), distributed over the Qinghai province, would have 10-20 seeds per pod more than that of common rapeseed, some of the multi-loculus materials had over 90 per cent multiloculus pod, and were the excellent regional rapeseed resource. Through the reciprocal crossing between B. juncea L. with multiloculus and B. napus L., and recurrent selecting among interspecific generations, 5 new B. napus L. with multi-loculus idioplasmic resources were bred, in which the multi-loculus pod rate could reach 76-96％, multi-loculus plant rate reached 83-98％; Seeds per pod reached 35-51, seed weight per plant reached 24-28.2g, it was increased 16.7-70％ and -2.4-14.6％ respectively by comparing to the conventional variety qingyou No.14; Besides all above, the content of erucic acid, glucosinolate and oil content of there materials were 3.2-0.6％, 35-27.6μmol/g and 40.18-42.59％ respectively.
