| 摘 要： | 本研究对油松无性系种子园 2 2个无性系的球果量和雄球花量进行观测调查 ,并对数据进行处理。通过无性系内和无性系间的方差分析、聚类分析和秩序排序法对各无性系进行分类和排序。研究结果表明 :无性系间球果量和雄球花量的差异极显著 ,而无性系内差异不显著。并筛选出 1 61 #,6#,2 9#,63 #,78#5个球果数量大 ,占总数的 46% ,雄花量高 ,占总数的 5 7.6%的无性系为优良无性系 |

| Abstract: | Observation and investigation have been done on strobile and staminate flowers of 22 clone in clonal seed orchard of Pinus tabulaeformis Carr.. According to variance analysis, clustering analysis and ordination method in and among clones, the clones have been classified and arranged in order. The results show: the difference between quantity of strobile and staminate flowers is remarkable with nonremarkable difference among clones. Five clones of No. 161, No.6, No.29, No.63, and No.78 are chosen as good clone with large quantity of strobile and staminate flowers, taking up 46 percent and 57.6 percent of the total separately. |
