一、前言茶树属异花授粉植物,基因型系杂结合,在一个庞大的种群内,让其自由授粉,配子随机组合,並没有外来不良因素的干扰,历代长期繁衍下去,后代性状将会保持平衡稳定不变。但个体间在形态和生理上必将产生出明显的差异,这种差异的程度和范围,往往与种群内贮藏基因种类的多少有直接关系。如果各种基因频率在每一世代的群体中,都保持为恒定 I. Introduction Camellia cross-pollination plants, genotype Department of hybrid, in a large population, let it free pollination, gametes random combinations, and no external adverse factors interfere with the long-term proliferation of generations, the offspring traits will remain Balance stable. However, there are bound to be significant morphological and physiological differences between individuals. The extent and scope of such differences are often directly related to the number of stored genes in the population. If a variety of gene frequencies in each generation of the population, remain constant
