Inheritance of fertility for cytoplasmic male sterility of new material RM5637A in rapeseed ( Brassica napus L.)

Hou Yan

Abstract

The inheritance of fertility for cytoplasmic male sterile material RM5637A were studied by using the crosses between RM5637A and maintainer, restorers of Polina CMS and Shan 2A CMS, GMS line, cultivars in Brassica napus L. The results showed that the inheritance background of RM5637A wasn't same with Polina CMS and Shan 2A CMS and GMS lines, RM5637A was a new cytoplasmic male sterile system. The sterilily of RM5637A were controlled by 3 pair recessive gene of independent inheritance. The restorers have 73.3% of cultivars in Brassica napus L.
