Abstract:According to the sensitivity of male sterility to temperature, 35 polima CMS lines were divided into three groups: ( 1 ) high temperature CMS line ( 62.9% ) ; ( 2 ) low temperature CMS line ( 28.6%) ; ( 3 ) stable CMS line ( 8.5%). THe temperature sensitivity of polima CMS depends critically on the genotypes of the maintainers. This means that it is possible to breed stable polima CMS lines. The devepoment of winter rapeseed CMS line is more difficult than that of spring rapeseed CMS line. The restoring genes ( Rf ) of polima CMS were found in B. napus, B. juncea, B. campestris, suggesting that the Rf gene exist on the "aa" chromosome. The heterosis of polima CMS hybrids is significent and common in some characters tested especially in the plant seed yield and number of siliqua per plant. Cytoplasm of polima did not have adverse effectson the F_1 characters tested. The author suggest that the success in development of CMS "three lines" is closely related to the origin and evolution of rapeseed, and it may be relatively easy to find CMS and its restorers in the centers of origin and nearby, and to find maintainer in regions far from the original centers.
