为缩短小麦育种年限,一般采用一年多代以加快世代进程和越级提升加快试验进程两种途径。由于小麦杂种后代要经历一个性状的分离和纯合稳定过程,两者比较还是加快世代进程见效最快。国外利用人工气侯室结合种子处理,能使小麦一年繁殖4—5代。我国北方不少育种单位到南方进行加代繁殖,耗费人力物力较多。为此,我们曾于1976年在偃师县周山,灵宝县的福地、胡坡,
In order to shorten the breeding period of wheat, we usually adopt more than a year and several generations to speed up the generation process and upgrade the test to speed up the process. Since the offspring of wheat hybrids undergo a trait separation and homozygous stability process, the two are more effective in accelerating the generational process. Foreign use of artificial climate combined with seed treatment, wheat breeding 4-5 generations a year. Many breeding units in the north of our country go to the south for additional breeding and spend more manpower and material resources. To this end, we have in 1976 in Yanshi County, Zhou Shan, Lingbao County blessed land, Hu Po,
