Abstract

In the three-year nursery testing , 8 of 41 clones are selected and ranked randomly .Their nursery terms are tested .The results are as follows :①The broad-sense heritabilities of height , diameter and volume of cloned seedings are 0.897 8 , 0.831 4 and 0.808 1 respectively ;genetic variation coefficients are 15.82 %, 14.02 % and 41.12 %.It is possible to select excellent clones .②The correlation coefficients among heredity , appearance and environment of height , diameter and volume are high .These three properties can be excellent selected properties .The analysis of correlated heritability and correlated genetic variation contribution rate shows that the selection of height is superior to those of diameter and volume .③4 clones including No.7 , No.11 , No.27 and No.28 are selected from 8 clones .The genotypic gains of height , diameter and volume are 36.99 %, 35.51 % and 139.93 % respecitvely .[ Ch , 6 tab .7 ref .]
