[Objective] The study aimed to introduce and screen the broccoli variety fitted to the climate environment of Ningbo region, with high-yield, disease resistance and high-quality as the main objectives. [Method] In the experiment of broccoli variety, 9 varieties with early ripening, middle ripening and late ripening varieties were compared and their botanic traits, phonological phases, disease resistances, commerical qualifies and yields were investigated. [ Result] The vine ta green, excellence and green band possessed compact plant type, their single ball weights and yields per 667 m^2 both possessed developmental space and their growth potential, heat resistance, damp resistance and disease resistance performances were best and their flower ball qualities were fine. [ Conclusion] From viewpoint of long-term development, the vine ta green, excellence and green band with export prospect and higher economic value to demonstrate and popularize should be chosen in Ningbo district.
