摘  要：
选择优良无性系,是竹柏遗传改良的重要途径之一。无性系测定结果表明,表型优株建立的竹柏无性系间,千粒重、单位面积种子产量、种子含油率均存在极显著差异,进一步选择是必要的;竹柏千粒重、单位面积种子产量、种子含油率无性系重复力分别为0.885,0.784,0.804。通过聚类分析,根据3个主要经济性状的综合表现,精选获得的SM2,NS1,NY2,SM1等4个优良无性系的千粒重、单位面积种子产量、种子含油率等性状,与参试群体总体水平比较,遗传增益分别达15.68%,50.62%,5.55%,与CK比较,遗传增益分别达32.38%,638.10%,10.68%,且均具较强适应性和较高稳定性。NS1,SM2适宜中等以上的立地条件,即在Ⅰ、Ⅱ类地适宜推广;NY2,SM1适宜在Ⅰ,Ⅱ,Ⅲ类地推广。

摘  要：
One of the important channels for genetic improvement is to choose clones of excellent performance. The results of selecting clones showed that there was highly significant difference in thousand seed weigh,seed yield per unit area and seed oil ratio of phenotypic excellent clones of Podocardpus nagi.Their repeatability was 0. 885,0. 784 and 0. 804 respectively,which was necessary to choose. Compared with the overall level of sampling groups according to the comprehensive performance of three main economic traits,four clones of excellent performance were selected carefully i. e. SM2,NS1,NY2 and SM1 with stronger adaptability and higher stability. The genetic gains of thousand seed weigh,seed yield per unit area and seed oil ratio were 15. 68%,0. 62% and 5. 55% respectively,but 32. 38%,638. 10% and10. 68% compared with CK by the method of cluster analysis. The site conditions of Types Ⅰ and Ⅱ are suitable for the clones of NS1 and Sm2 and the site conditions of Types Ⅰ,Ⅱ and Ⅲ for NY2 and SM1.
