我所从1973年开始,连续七年进行南繁.南繁的好处,一是加代,二是扩繁,三是异地条件有利于淘汰和选择.在南繁的启发下,我们从1975年开始试验春麦就地夏播加代,1982年正式将其应用于育种实践.1982—1984年,我们就地夏播加代的400余份材料,有处于分离的低代杂交材料,有性状基本稳定的高代材料,也有扩繁的育成品系,都取得了较好的效果. Since 1973, we have been carrying on the prosperity of Nanfan and Nanfan for seven consecutive years, one is Gadai, the other is the expansion, and the other is that off-site conditions are conducive to the elimination and selection. Under the inspiration of Nan Fan, we started in 1975 Spring wheat trial was conducted in summer and was formally applied to breeding practice in 1982. From 1982 to 1984, we added more than 400 pieces of summer sowing material on site, with low-generation hybrid materials in isolation and stable high traits On behalf of the material, but also the proliferation of breeding products, have achieved good results.
