- 摘要:
- 以内蒙古克什克腾旗种源10个家系的西伯利亚杏为试材，采用多元统计分析方法，对西伯利亚杏的果实、杏核、杏仁、株高与地径共17个表型性状进行了研究，以期为内蒙古西伯利亚杏的选育及遗传改良提供了理论基础。结果表明：10个家系间所有性状均存在极显著差异，不同性状的变异系数幅度为0.01～0.28，果重变异系数最大为0.28，地径的变异系数最小为0.01；前3个主成分累计贡献率达到84.86%；聚类分析清楚地将10个家系分为3组，散点图分析与聚类分析结果一致。
- Abstract:
- Taking 10 families of Siberian apricot in Hexigten provenance of Inner Mongolia as the test materials，17 phenotypic traits of the fruits，kernel，almond，plant height and ground diameter from Siberian apricot were studied by using multivariate statistical analysis.The results of the study provided a theoretical basis for breeding and genetic improvement of Inner Mongolia Siberian apricot.The results showed that all characters existed significant differences in the 10 families，amplitude of variation coefficient between different traits was 0.01-0.28，the maximum variation coefficient was weight(0.28)，the minimum variation coefficient was plant height(0.01)；the first three principal components cumulative contribution rate of 84.86%；cluster analysis divided clearly 10 family into three groups，scatter plot analysis using two main factors also strongly confirmed the cluster analysis results.
