Research progress of Chinese rose breeding techniques

Abstract

Chinese rose is one of the top ten most famous traditional flowers in China, as well as one of the world's four cut flowers and the most frequently used ornamental flower, known as the "queen of flowers." According to the records of the American Rose Association, in 2000 there were more than 24,000 varieties of Chinese roses worldwide. In China, the Chinese rose has a lengthy history of cultivation, a strong mass base, a positive moral symbol, and a robust group of varieties. In recent years, an increasing number of plant breeders have been devoted to the study of Chinese rose breeding, and Chinese rose breeding techniques have advanced by leaps and bounds and produced fruitful outcomes. This paper summarized the breeding objectives of contemporary Chinese rose, analyzed and discussed the breeding techniques of molecular breeding, introduction and screening, crossbreeding, bud sport breeding, mutation breeding, and so on, and anticipated the future research field of Chinese rose breeding.
