甘蓝(Brassica oleracea L.)是我国各地普遍种植的一种重要蔬菜。国内外大量资料证明,通过杂交育成一代杂种或新品种是提高甘蓝生产水平的一条重要途径。我单位自1970年以来开始进行甘蓝杂种优势利用的研究,并与北京市农科院等单位协作先后育成“京丰1号”、“报春”、“秋丰”、“庆丰”、“晚丰”、“双金”、“园春”等7个早、中、晚熟配套的甘蓝一代杂种在生产上大面积推广应用。众所周知,亲本品种或自交系配合力的
Brassica oleracea L. is an important vegetable commonly planted throughout China. A large number of domestic and foreign data prove that breeding hybrids or new varieties by crossing is an important way to increase the production level of cabbage. My unit since 1970 began to carry out research on the utilization of cabbage heterosis, and with the Beijing Academy of Agricultural Sciences and other units have collaboratively bred “Jing Feng 1”, “Primula”, “Autumn Feng”, “Qingfeng”, “ Seven varieties of early, middle and late maturity cabbage F1 hybrids were popularized and applied widely in production, such as ”late abundance“, ”double gold“ and ”garden spring". As we all know, the parental varieties or inbreds with the ability
