奶白菜核基因雄性不育系的选育与利用
Breeding and Utilization of the Genetic Male Sterile Line in Milk Chinese Cabbage
摘要
Abstract
In order to resolve the problem that cross breeding and production of hybrid in milk Chinese cabbage. According to the hypothesis of multiple allele inherited genetic male sterile, A genetic male sterile line of Chinese cabbage with green stipe 00S107 was used as a source of male sterility,and methods of continuous backcross-ing and identifying of the genotypes were applied to transfer the male sterile line of milk Chinese cabbage. Hybridized combinations were obtained by the male sterile line as female parent cross with excellent self-line and we analysed the hybrid vigor. A new genetic male sterile line GMS3 with 100% male sterile plants and 100% male sterility was obtained. Two excellent hybridized combinations GMS3 × B1 ,GMS3×B2 were selected, whieh is uniform and superior to CK in yield. Directional transfer model which transfer sterile gene and horticultural characters at the same time resolved the puzzle that breeding and utilization of the genetic male sterile line in milk Chinese cabbage.关键词
