花药培养单倍体育种技术,在实际应用上的潜力日益显示出来。目前,应用这项技术培育的一批小麦新品种(系)已在生产上大面积推广应用。但是,这种潜力只有在单倍体植株加倍成纯合二倍体之后才能充分发挥。近年来,我国科学工作者对花粉植株染色体加倍方法,进行过多种试验研究。据文献报道:以秋水仙素直接浸根应用最多,但死苗率高,效果不够理想;用秋水仙素和二甲基亚砜(DMSO)混合处理单倍体植株,加倍结实有明显提高,但尚不稳定;应用阳畦盖膜,冬季低温刺激加倍,方法简便,虽收 Anther culture haploid breeding technology, the potential for practical application has become increasingly evident. At present, a batch of new wheat varieties (lines) developed by applying this technology have been widely applied in production. However, this potential can only be fully realized if haploid plants are doubled to homozygous diploids. In recent years, scientists in our country have doubled the chromosome number of pollen plants and conducted various experimental studies. It is reported in the literature: direct application of colchicine root direct application, but the dead seedling rate is high, the effect is not ideal; with colchicine and dimethyl sulfoxide (DMSO) mixed treatment of haploid plants, doubling and fruiting was significantly improved, But not yet stable; the application of Yang cap membrane, double the winter cold stimulus, the method is simple, although the income
