摘　　要：[目的]为安徽省优质油菜新品种的审定和推广种植提供依据。[方法]以皖油14为对照,研究06-P230、6-P24、06-崇8、06-崇11、06-崇42、06-崇47、ND8804共7个甘蓝型杂交双低油菜新品系在安徽地区的适应性、产量及经济性状。[结果]06-崇8的产量最高,平均为3 350 kg/hm2,比对照增产12.29%。06-崇420、6-P24、ND8804、06-崇11分别比对照增产9.12%、7.07%、6.89%、1.67%。06-P24的有效角果数最多,为538.6个。ND8804的每角粒数最多,为24.0粒,其次是06-崇42。06-崇8和06-P24的熟期早,分别比对照早2.00、1.33 d。06-崇8的菌核病发病率最低,为11.88%。ND8804的抗倒性强。[结论]06-崇8、06-崇420、6-P24和ND8804新品系的经济性状协调,丰产性好,适应性广,抗倒性较强,可进一步参加省区域试验。[Objective] The study was to provide the basis for the registration and popularization of new variety rape with good quality in Anhui Province.[Method] With Wanyou 14 as CK,the adaptability,yield and economic characters of 7 new strains（06-P23,06-P24,06-cong 8,06-cong 11,06-cong 42,06-cong 47 and ND8804） of hybrid rape（Brassica napus L.） with double low in Anhui region were studied.[Result] The yield of 06-cong 8 was the highest,being 3 350 kg/hm2 in average and increasing by 12.29% than that of CK.The yields of 06-cong 42,06-P24,06-cong 8,ND8804 and 06-cong 11 were increased by 9.12%,7.07%,6.89% and 1.67% than that of CK resp.The effective pod numbers of 06-P24 was the most,being 538.6 pods.The grain number in per pod of ND8804 was the most,being 24.0 grains and the following was that of 06-cong 42.The mature periods of 06-cong 8 and 06P24 were early,being 2.00 and 1.33 d earlier than that of CK resp.The incidence of sclerotinia rot in 06-cong 8 was the lowest,being 11.88%.The lodging resistance of ND8804 was strong.[Conclusion] The new strains of 06-cong 8,06-cong 42,06-P24 and ND8804 had the concordant economic character,good prolificacy, wide adaptability and strong lodging resistance,which could be experimented at the provincial regional test further.
