| Abstract: | Based on the determination of cross full-sib and determination of open-pollinated half-sib of Cunninghamia lanceolata in the first generation seed orchard,the selection method,the parental origin and genetic characteristics of superior clones of C.lanceolata（second generation superior trees） were studied.There were 40 selected superior clones of C.lanceolata identification with Variety Approval Committee of Hunan Tree Seed and Seedling in September 2010,and got the forest seed certificate issued.Those superior clones were divided into five types with their genetic characteristics,such as less sections（or no section） wood type,red wood type,close planting wood type,hard planting situation wood type,and flowering and fruiting performance type.Those superior clones of C.lanceolata were promote graft in the second generation seed orchards in Hunan Province. |
