华北落叶松种子园无性系雌花量与选优性状的相关分析

摘要

利用DPS数据处理系统对华北落叶松种子园无性系的雌花量与其他性状进行遗传力测定、遗传相关分析、遗传通径分析和间接选择效率分析,结果表明,无性系的雌花量与其他测试性状相关不显著,尤其树高、材积的生长反而抑制了雌花量,且雌花量的间接选择效率较低.%Using DPS,Through measuring heredity power、analyzing heredity correlation、nalyzing heredity pathway and analyzing efficiencyof indirect seletion, the female flowers' quantities had indirectly correlations with other characters, especially the height of trees and the bunkprevented growth of the female flowers' quantities. The efficiency of indirect selection of it was low.
