自然界高等植物的单倍体是经过不正常的受精过程出现的,单倍体出现的频率很低。近年来,由于组织培养技术的发展,通过人工诱导或种属间杂交产生单倍体的途径主要有以下几种。1花药培养花药培养是把发育到一定阶段的花药接
Haploids in higher plants in nature occur through abnormal fertilization processes, and haplotypes appear to be low frequency. In recent years, due to the development of tissue culture technology, there are mainly the following ways to produce haploid through artificial induction or cross-species hybridization. 1 anther culture Anther culture is to develop to a certain stage of anther then
