常规育种的目的是要在杂交后代中通过自然选择与人工选择分离出优良纯系,并使之成为品种,这个过程在不进行加代的情况下需要10年左右的时间,育种过程过长。实行一年两代繁育,是加速小麦育种进程的一条重要途径。由于中试以后的程序必须在规定的特定区域内进行,一年只能试验1次,因此,如要加快小麦育种速度,只能从缩短育种前期人手,即亲本杂交组配、F_1代及稳定系进行加代。作者与中国农科院老师就半冬性
The purpose of conventional breeding is to isolate the fine pure lines by natural selection and artificial selection in hybrid progeny and make them into varieties. This process takes about 10 years without addition and the breeding process is too long. Implementing two generations of breeding a year is an important way to accelerate the process of wheat breeding. Since the post-pilot program must be carried out within the specified area and can only be tested once a year, it is only necessary to shorten the period of pre-breeding staffing, that is, the parental crossover, F 1 generation and stability Department of the Canadian generation.
