杉木是我国南方重要用材树种,栽培历史您久,在自然界中存在着许多优良类型。通过杉木花药培养,取得单倍体植株,将染色体加倍进而获得纯合二倍体花粉植株。这样,在短期内获得各类型纯系。在此基础上,进行纯系的选择和杂交,可以选育出速生、半产、优质、抗性强的有性系,为杉木培育新品种开辟一条新的途径,也能为研究 Cunninghamia lanceolata is an important timber species in south China. It has been cultivated for a long time and many good types exist in nature. Through fir anther culture, haploid plants were obtained, doubling chromosomes and obtaining homozygous diploid pollen plants. In this way, various types of pure lines are obtained in a short period of time. On this basis, the selection and crossbreeding of pure lines can breed fast-growing, semi-productive, high-quality and resistant sexual lines, which opens up a new way for cultivating new varieties of Chinese fir,
