将新选育的 4个晚抽薹大白菜品系及 3个对照品种露地春播 ,结果比较表明 :4个新品系在经济性状、产量、耐抽薹性等方面均优于对照 ,并各具优点。 3号品系产量高 ,包心早 ;2号品系净菜率高 ,耐抽薹性强 ,商品性好 ;4号品系抗病性强 ,经济性状良好 ,耐抽薹性强 ;1号品系在比较的几个方面相对于2、3、4号品系虽不突出 ,但明显优于对照品种。 Four late bolting Chinese cabbage varieties and three control varieties were sowed in spring and sowed in spring. The results showed that the four new lines were superior to CK in economic traits, yield and bolting resistance, and had their own advantages. No.3 strain had high yield and early inclusion; No.2 strain had high net food rate, strong bolting resistance and good commercial properties; No.4 strain had strong disease resistance, good economic traits and strong bolting-resistance; Relative to the two strains 2,3,4, although not prominent, but significantly better than the control varieties.
