一种测定遗传差异的新方法

A NEW METHOD OF MEASURING GENETIC DIFFERENCES

  • 摘要: 测定了甘蔗亲本间的10项遗传差异,并对遗传差异指标进行了主成分分析。在保证特征根累积贡献率达88%的基础上,选取前三个特征根和相应的特征向量,计算出供试28个组合的前三个主成分值;还研究了前三个主成分和杂种主要经济性状的相关,对所阐述的研究方法开展了讨论。
    Abstract: The genetic differences between sugarcane parents were estimated by ten genetic divergence criteria, and principal component analysis was performed on these ten divergence indices of 28 combinations. The first three eigenvalues and corresponding eigenvectors of the principal components which accounted for more than 88 % of the total variation of all the indices were selected. The first three principal component values of each cross were caculated, and the relationship between the first three principal components of the crosses and major economic characters of the hybrids were investigated. The research methods described were discussed.
