| 摘要: |
| 46个麻疯树半同胞家系试验表明，在相同种植管理条件下，不同家系间、家系内的平均树高、冠幅、分枝数、结实量有极显著差异。经多重比较分析可知，家系159，114，119及131号各性状指标均较好，可入选为早期表现优良的家系。以树高和冠幅大于2.0 m、结果数量大于120颗、种子千粒质量大于500 g为标准进行优良单株初选，共选出13株优良单株，可做为进一步无性系测定或育种的材料。 |

| Abstract: |
| Results from the progeny test of Jatropha curcas including 46 families showed that differences among families for height, crown width, branch number and fruit amount were all significant. Duncan′s Multiple Range Test showed that No.159,114,119,131 were selected as superior families with fine characters. Thirteen superior trees were selected by using the criteria with height and crown width were more than 2.0 cm, respectively, the fruits was more than 120 pellets, and weight of thousand grains was more than 500 g. These superior individuals can be vegetatively propagated for clonal test or used for the follow-up breeding. |
