摘要
于1986~1994年,利用现有青菜种质资源,通过杂交实现基因重组,并经连续多代自交纯化,选育出两个高代自交系,自交系间再杂交复配育成了一个新品种“小叶青”。每一自交子代及最终配制的组合均严格进行室内、田间“三抗”性(抗TuMV、霜霉病和黑斑病)鉴定。所育成的“小叶青”抗病性强,商品性状与市场要求相吻合,产值比“矮抗青”提高20%左右。
This paper shows that a new variety'Xiaoyeqing'was bred by hybridizing of two self-lines which were obtained by high generations' self-pollination purification using existing materials of nonheading Chinese Cabbage during 1986~ 1994. The disease resistance identification including TuMV, downy mildew and black spot disease must be tested indoors and outdoors among all of the self-pollinated descendents and hybridized combinations. The new variety 'Xiaoyeqing' has such advantages as fine shape, short petiole, high disease-resistance. It accords with the market demands and its output value is 20 percent higher than that for 'Aikangqing'.
