AbstractTo screen out high qualityand high yield Brassica rapa varieties suitable for cultivation in Wuhu，Anhui Province，10 Brasica rapa varieties，namely Zheyou 28，Zheshuang 72，Quanyinyou 7101，Deqiyou 4，Quanyinyou5， Qingyou8，Ning R101，F(xiàn)engyou 306，Xiaoyou 737，and Liangyou 100，were selectedforvariety comparison experimentsfrom 2022 to2O23.Its growth period，resistance，yield composition factors and yield were determined.The results showed thatthe total growth period ofeach varietyranged from 214to 231days，among which Quanyinyou5had thelongesttotalgrowth period，whichwas231days.Theentire growthperiodof Xiaoyou737wastheshortest，which was 214 days. In terms of cold resistance，eight varieties such as Zheyou 28，Zheshuang 72，and Quanyinyou 7101 had relativelygood coldresistance.In termsof lodging resistance，6varieties including Zheyou 28，Zheshuang 72，and Quanyinyou71O1 had strong lodgingresistance.Theincidencerates of sclerotinia of variousvarieties ranged from （2號 10.26% to 18.25% ，and the disease index ranged from 2.15 to 4.50. The plant height of the tested rapeseed varieties was117.7-170.1cm.The effective number of plantsof each variety at maturitywas125 O00-210O0O plants per hectare.The effective numberof branches per plant was 8.0-15.0.Theefective numberof kernels per plant was 80.0- 370.1.The numberof kernels per kernels was 18.5-23.3.The thousand-grain weight was 3.5-5.3 g. The output ranged from 1 416.0 to 3972.8kg/hm2 .In conclusion， Zheyou 28， Zheshuang 72， Deqiyou 4 and Qingyou 8 had performed well overall，with high yieldsand good highyield properties，making them suitable forpromotionand cultivation in the Wuhu area.
