在作物育种工作中,新品种(系)的出现速度是与育种材料的世代进程密切相关的。小麦就地夏繁就是在育种过程中,把在正常季节生长和收获的小麦,在当地条件下于当年再繁殖一代,以加速育种材料的世代进程,提早育成新品种。现根据我们的初步实践,就小麦就地夏繁中几个问题,谈一些看法。 一、小麦生长发育与我省夏季环境的主要矛盾 In crop breeding, the emergence of new varieties (lines) is closely related to the generational process of breeding materials. In the summer wheat is flourishing in the breeding process, in the normal season of growth and harvest of wheat in the local conditions in that year breeding again in order to accelerate the generation of breeding materials, early breeding new varieties. Now based on our initial practice, we will talk about some issues concerning wheat in summer and in the middle of the country. First, the main growth and development of wheat and summer environment in our province
