春甘蓝为春夏季主要叶菜类蔬菜之一,早熟春甘蓝对弥补春淡季蔬菜种类之不足有重要作用。目前生产上应用的早熟春甘蓝品种多为鸡心,虽具有早熟不易产生先期抽薹等优点,但整齐度较差,产量较低。选育早熟、丰产、耐寒、冬性强、商品性好的春甘蓝品种是甘蓝育种的目标之一。我们以鸡心为基本材料,通过自交不亲和系选育和组合力测定,育成了早熟春甘蓝一代杂种——春丰,经省区域试验和生产试验证明,春丰较鸡心显著增产且整齐度高,1986年初由省品种审定委员会审定通过并正式定名。
Spring cabbage is one of the main leafy vegetables in spring and summer. Early spring cabbage plays an important role in making up the shortage of vegetables in spring and autumn. At present the production of early spring cabbage varieties are mostly chicken heart, although not easy to produce premature bolting and other advantages, but the less uniform, lower yields. Breeding of precocious, high yield, hardy, strong winter, good commercial varieties of cabbage is one of the objectives of cabbage breeding. We use chicken heart as the basic material, bred early spring cabbage F1 hybrid by spring self-incompatibility line selection and combination determination, Chunfeng, the provincial regional trials and production tests showed that Chunfeng significantly increased yield and tidy than chicken heart High degree, early 1986 by the provincial varieties approval committee approved and formally named.
