Summary:A method for breeding new purple-orange Chinese cabbage germplasm crosses the purple head Chinese cabbage inbred line 11S96 as the male parent and the orange Chinese cabbage inbred line 11J11 as the female parent. On the basis of selecting individual plants with good heading property in the F2 population, molecular markers are used to select individual plants carrying the purple-head gene and the orange gene. Through selfing of individual plants for three consecutive generations, a new Chinese cabbage germplasm with green outer leaves and purple-orange head leaves is bred. This method aggregates the purple-head gene and orange gene which are expressed in the head leaves of Chinese cabbage, creating a new Chinese cabbage germplasm with purple-orange head leaves. It enriches Chinese cabbage breeding materials, lays the foundation for breeding the new purple-orange Chinese cabbage variety, and sets a precedent for the aggregation of the head color traits of Chinese cabbage.
