在培育小麦新品种中,当前国内外主要采用有性杂交的方法,从随机分离的大量群体中选择纯合材料。一般所需年限较长。运用花药培养花粉单倍体植株,经染色体加倍,一次能获得高纯合的二倍体植株。所获花粉植株后代可根据育种目标进行选择而培育出新品种,提供生产上应用。因此,花药培养已为育种工作者所重视。目前,烟草、粳稻的花药培养技术已达到能用于育种的水平。但小麦花粉植株的诱导频率还不高。花粉植
In cultivating new wheat varieties, the method of sexual crossbreeding is mainly adopted at home and abroad to select homozygous materials from a large number of randomly separated groups. Generally longer life expectancy. Pollen haploid plants are cultured with anther, doubled by chromosomes, and once obtained high-purity diploid plants. The progeny of the pollen plants obtained can be bred according to breeding objectives to breed new varieties and provide the production application. Therefore, anther culture has been valued by breeders. At present, the anther culture technology of tobacco and japonica has reached the level that can be used for breeding. However, the induction frequency of wheat pollen plants is not high. Pollen plant
