摘要：木麻黄科（Casuafinaceae）植物有4属96个种，天然分布于东南亚、大洋洲和太平洋群岛，具有速生、抗风、固沙、耐盐碱和瘠薄等特点，其中，
According to genetic analysis on 6 traits of 4-year-old Casuarina glauca in provenance trial which estab- lished in Lin＇gao County, Hainan Province, there were significantly differences among height （H）, diameter at breast height （ DBH）, individual volume （ VOL）, stem straightness （SS） and survival percentage （SP） （p 〈 0.05 or p 〈0.01）, but not in stem axis persistence （SA） （p 〈0.05）. The heritability of the six traits varied from 0.02-0. 55, of which SS 0.55, SP 0.48, H 0.28, DBH 0.17, VOL 0.10, the lowest one was 0.02 in SA,so the first five traits can be used as single trait selection for C. glauca provenances. The genetic correlation among the three growth characteristics, H, DBH and VOL was highly significant, but not among quality traits, SA, SS and SP, which showed that the three quality traits were independent from each other. In another aspect, the coefficient of variation varied from 31.5% （survival percentage） to 91.8% （height）. Additionally, the mean genetic gains in the five traits were 2.1%, 1.4%, 2.2%, 0.2% , 0.2% and 6.2% respectively. By means of Smith-Hazel Index Selection and 20% selective ratio, five seedlots, G03, G02, G19, GO7 and G25 were screened out as superior provenances for further tree breeding research.
