摘　　要：本文对2017—2018年度长江中游区11个国家油菜新品种的农艺性状与单株产量进行灰关联熵分析。结果表明,各性状与单株产量的熵关联度为硫苷0.9793、菌核病发病率0.9808、菌核病发病指数0.9806、株高0.9863、有效分枝数0.9734、单株产量0.9894、千粒重0.9807、角粒数0.9848、单株有效角数0.9876;熵关联顺序为单株产量、单株有效角数、株高、角粒数、菌核病发病率、千粒重、菌核病发病指数、硫苷、有效分枝数,本结果可为长江中游区杂交油菜品种选育指明方向。Grey relation entropy analysis was carried out on the yields and correlated characters of 11 new national rape varieties in the middle reaches of Yangtze River from 2017 to 2018.The results showed that the entropy relation grade between each character and yield was as follows:the thioglycoside was 0.9793,the incidence of sclerotinia was 0.9808,the index of sclerotinia was 0.9806,the plant height was 0.9863,the effective branch number was 0.9734,the yield per plant was 0.9894,the 1000-grain weight was 0.9807,the seed number per pod was 0.9848,and the effective pod number per plant was 0.9876.The entropy relation order was yield per plant,effective pod number per plant,plant height,seed number per pod,incidence of sclerotinia,1000-grain weight,index of sclerotinia,thioglycoside,effective branch number.Accordingly,the breeding direction of hybrid rapeseed varieties in the middle reaches of the Yangtze River can be determined.
