Abstract: Restoring ability for Radish-cytoplasm Rape (Brassica napus) male sterile lines was discovered in Vegetable A and its hybrid progenies in March, 1984. From the plants mentioned above 5 complete restorers were screened out during summer propagation in Kunming, Yunnan Province in the same year. This has laid the fundation for obtaining the complete set of the "Three Lines" of Radish-cytoplasm Rape (Brassica napus).The first discovery of the restorative origin has satisfactorily solved the problem at home and abroad that the male sterility is accompanied with a lack of chlorophyll in the central leaves.
