Abstract: | The genetic variations and correlations of clonalstem growth and branchingtraits were studied.The direct and indirect ertects ofthe traits to stem volume growthwere e-valuated.For objective of timber production by clonal forest of Pinus tebureaformis,the gen-eral select index methods was emploied.Analysis of select effience among deffernce select in-dex show that the common select index was more efficency in multi-traits selection. |
