青研1号是青岛市农业科学研究所利用引进的国内外耐热大白菜,通过多代自交分离选择的方法,在育成自交不亲和系的基础上,进行测交选育而成的早熟耐热大白菜一代杂种。1995~1996年山东省夏大白菜区域试验结果,二年五个试点平均亩产4056kg,略高于对照夏阳,1997年全省生产试验,平均亩产4465.9kg,比对照夏阳增产26.5%。1998年经山东省农作物品种审定委员会审定定名,现已大面积示范推广。
Qingyan 1 is the Qingdao Institute of Agricultural Sciences using the introduction of domestic and foreign heat-resistant Chinese cabbage, through multiple generations of self-selection method of selection, breeding self-incompatibility based on the cross-breeding The precocious heat-resistant Chinese cabbage generation hybrids. From 1995 to 1996, the regional test results of summer Chinese cabbage in Shandong Province showed that the average yield per mu of 4056kg in five pilot projects in two years was slightly higher than that of control Xiayang. In 1997, the province’s production test averaged 4465.9kg per mu, 26.5% more than the control. 1998 by the Shandong Provincial Crop Variety Approval Committee naming, is now a large area demonstration and promotion.
