优势育种是提高甘蓝生产水平的重要途径之一。我们自从1070年开始甘蓝杂种优势利用的研究工作以来,已经选育出一批早熟甘蓝的自交系和自交不亲和系。了解它们的表现及配合力的优劣,无论对选择亲本配制优良组合,还是常规育种都是非常重要的。因此,最近几年我们对一部分早熟、中 Advantage breeding is one of the important ways to improve the production level of cabbage. We have bred a group of early-maturing cabbage inbreds and self-incompatible lines since we started the research on the utilization of cabbage heterosis in 1070. Understanding their performance and the merits of combining ability, whether it is a good combination of selection of parents, or conventional breeding is very important. Therefore, in recent years, we are part of the precocious, medium
