Introduction of Cabbage(Brassica oleracea var.capitata L.)Variety and Screening of Root Inducing by Axillary Shoots in Hainan
Cabbage(Brassica oleracea)is one of the crucial leafy vegetables in China.To enrich the variety re-sources of leafy vegetables in Hainan and meet the demands of consumers and the market for high-quality and high-yield varieties,this study introduced and evaluated ten cabbage varieties.The evaluation covered agronomic traits,ball-forming traits,yield traits,and disease resistance.Additionally,the study explored methods for root and flowering induction of axillary bud seedlings.The goal was to establish a self-sustaining cabbage breeding system in Hainan Province.The comprehensive evaluation revealed that'Zhonggan602','Zhonggan606','Zhonggan608','Zhonggan828'and'21C12'had better overall characters and commercial with good resistance to ball splitting.These varieties are suitable for basic breeding materials of cabbage breeding in Hainan Province,and can also be popularized in selected regions.The study found significant differences in rooting performance of axillary bud seedlings among different varieties of B.oleracea and among different strains of the same variety,indicating that axillary sprout inducing rooting traits had not been selected by breeding.By thoroughly screening strains with good rooting characteristics from axillary bud seedlings and combining this with indoor light-temperature-induced flow-ering or utilizing the low temperatures in the northern mountainous area of Guilin City,Guangxi Province,a pre-liminary cabbage breeding system for Hainan Province could be established.This would create conditions for the future development of new cabbage varieties adapted to the southern ecological climate.
