甘蓝除作蔬菜食用外,也广泛用作奶牛、牲猪的青饲料。但是,普通的平头甘蓝叶球水分多,养分相应偏低;由国外引进的一种饲用甘蓝虽不结叶球,但茎柱高大粗老,叶片稀疏,产量不高;两者作为青饲料均不理想。为了选育一种不结球、茎矮小、叶片多、养分足的饲用甘蓝,我们以青海省畜牧研究所的“1984”饲用甘蓝为母本,本地优良平头甘蓝为父本,进行杂交。将收取的杂交种子与父、母本种子分别于同年8月下旬播种,9月中旬移栽,亩栽3596株,栽培管理措施相同。据10月26日测定,杂交甘蓝平均茎柱高27.2厘米,比父本高12厘米,比母本低31.6厘米;每株叶片数24.6片,比父、母本分别多9.6片与10.2片;叶长28.8厘米比父、母本分别长2.4厘米与6.5厘米;叶宽26.3厘
In addition to cabbage for food, but also widely used as dairy cattle, pigs feed green. However, the common kale leafy water and more nutrients correspondingly low; introduced from abroad, although a kelp not knotted ball, but tall stem coarse, sparse leaf, yield is not high; both as green forage not ideal. In order to breed a non-ball, short stalk, leaf more, nutrient-rich feed cabbage, we use the “1984” of Qinghai Provincial Institute of Animal Husbandry as a female parent of Cabbage, . Will receive the hybrid seed and parent and maternal seeds were sowed in late August the same year, transplanting in mid-September, mu planted 3596 plants, the same cultivation and management practices. According to the determination on October 26, the average stem height of hybrid cabbage was 27.2 cm, 12 cm higher than the male parent and 31.6 cm lower than the female parent; the number of leaves per plant was 24.6, an increase of 9.6 and 10.2 more than the parent and the female, respectively; Leaf length of 28.8 cm longer than the parent and the female parent 2.4 cm and 6.5 cm; leaf width 26.3%
