油茶是我国南方特有的木本油料树种。它四季常青,枝叶繁茂,终年花果不离,结实年限长,经济价值高。因此,积极发展油茶生产,对于社会主义建设和改善人民生活均有很大的意义。油茶属于异花授粉植物,长期以来,多采用实生繁殖。在慢长的生长发育过程中,由于自然杂交,后代分化很大,产生了形态特征、生物学特性、经济性状及抗病虫性等多样性变累的混杂群体。因此为了建立有性或无性系种子园,为发展油茶生产提供良种,必须尽快地 Camellia oil-wood species that are unique to southern China. It is evergreen, lush foliage, inseparable from all year round, long fruiting time, high economic value. Therefore, actively developing the production of camellia is of great significance to the construction of socialism and the improvement of people’s lives. Camellia are cross-pollinated plants, long time, more use of real breeding. In the slow growth process, due to natural hybridization, offspring differentiation is very large, resulting in morphological characteristics, biological characteristics, economic traits and pest and insect diversity and other mixed populations. Therefore, in order to establish seed orchards of sexual or clonal origin and to provide good seeds for the development of camellia production,
