一、单倍体育种的意义和作用茶树是多年生异花授粉植物,在遗传上是高度杂合的,通过自交手段很难获得纯系。如果通过花药培养育成单倍体植株后,经过染色体加倍,就可在较短时间内获得纯系,并且有可能解决以下问题:①有利于茶树遗传理论的研究。因为茶树的基因型是高度 First, the significance and role of haploid breeding Tea tree is a perennial cross-pollination plants, genetically highly heterozygous, it is difficult to obtain by self-cross-line. If the haploid plants are bred by anther culture and then doubled by chromosomes, the pure lines can be obtained within a short period of time, and the following problems may be solved: ① It is conducive to the study of the genetic theory of tea trees. Because the tea tree’s genotype is height
