A genetic correlation and path-coefficient analysis of quantity of flowers and growth traits of Chin

  • 摘要: 对广西杉木无性系的总花量与树高、胸径、冠幅、冠高、树冠表面积进行了遗传相关及通径分析 分析表明:总花量与生长性状之间的遗传相关系数均为负值;用生长性状对总花量进行间接选择效率不高;总花量的相关变异小,性状比较稳定;相关遗传力通径分析表明,生长性状对总花量的直接作用与相关遗传力差异很大

     

    Abstract: The gross flowers and height, diameter, crown width, crown height,crown surface of Chinese fir clones in Guangxi area were investigated by genetic correlation analysis and path-coefficient analysis. The results show that the genetic correlation coefficients between gross flowers and growth traits were negative,it was inefficient when we selected gross flowers by growth traits,the correlation variation of gross flowers was little, the trait was stable,correlative heritability path-coeff...
