Study on Integrated Selection and Estimation of the Breeding Value in Eucalyptus wetarensis Provenances

The variance and genetic analysis results involving 6 Eucalyptus wetarensiss provenances showed that there were highly significant differences in growth and other characteristics among provenances. The heritabilities of provenances and individuals ranged 68.65%～93.45% and 42.20%～82.63% for different characteristics studied, respectively. Growth characteristics were closely correlated with branch size （BR） and under branch height （BH） and crown （CW） except stem form （SF） and the rate of survival (SUR). At an age of 4.5 year old, the mean value of individual volume （SV） of the fastest provenance （No.17931） was 0.089 70 m3 and 1.858 7 times of the worst provenance. The provenance （No.17834） owned the best form characteristics and survival rate. By using synthetical evaluation, three good provenances （No.17834, No.17831 and No.17835） were selected. Meanwhile, the breeding value of all provenances were also estimated.
