Study on establishing Cunninghamia lanceolata breeding poputation of the third generation
YU Rong-zhuo(State-owned Teaching Forest Farm of Nanping,Nanping,Fujian 353000,China)
By means of the sexual and cloning approaches such as hybridization,side TAC and self-TAC a large number of elite clones have been developed based on the second generation of seed orchard.291 fine genotypes including fast-growing wood,well-growing and high quality,well-cloning,high resistance,special phenotypes and fine varieties from original forest were selected form multiple perspectives,utilizations and purposes to establish the third generation of principal population of C.lanceolata breeding.Thus the genes-collecting area and test seeds orchard were set up.
