该项成果系以J78-09和E78-04的抗病单株,经多代自交并结合苗期人工抗性鉴定筛选法育成的二个高代自交系复配育成,该品种具有抗高温、抗病害(病毒病,白斑病、霜霉病等)、株型矮、品质优等特点,是一个适于作为鸡毛菜、火青菜、早秋青菜以及冬常菜栽培的多作型新品种,优于当地原主栽品种。一般可增产10％以上。秋冬青菜可增产30％左右;作鸡毛菜栽培生长期可缩短1—2天。“夏冬青”新品种,适应范围广,可多作栽培,受到本市郊区和江、浙广大生产者和消费者的欢迎,具有很高的经济价值。“夏冬青”的育成为蔬菜抗病、抗逆性育种开创了一条新路。
The result is that the two high-generation inbred lines bred from the resistant lines of J78-09 and E78-04 through multiple generations of selfing and combined with artificial resistance identification and screening at the seedling stage were bred with resistance High temperature, disease resistance (virus disease, leukoplakia, downy mildew, etc.), plant type short, excellent quality characteristics, is a suitable as chicken feather, fire green vegetables, early autumn vegetables and winter vegetables cultivated for many new varieties, Better than the original main cultivated species. General increase of more than 10%. Autumn and winter cabbage can increase about 30%; growing season can be shortened for 1-2 days. “Summer Holly” new varieties, to adapt to a wide range, can be more for cultivation, by the suburbs and Jiang, Zhejiang, the vast number of producers and consumers welcome, with high economic value. “Summer Holly” bred as vegetables disease resistance, resistance breeding has created a new road.
