Study on the Selection of 69 Asexual Tung Tree Families by Canonical Correlation Analysis

  • Received Date: 1997-11-26
  • This paper,according to the data of 69 asexual tung tree samples from the main tung origin areas all over the country,which are recorded continuously for 7 years in Jinhua experiemental site,completed the analysis of 12 factors including tree body,fruits and their economic value and their contributions by canonical correlation analysis method. The canonical correlations of comprehensive growth factors and comprehensive oil productivity factors are studied. Based on the canonical correlation value from the model of each sample,a sample distribution chart was created and all the samples are clustered as 4 groups.The oil percentages are 238.6% 187.7%,112.3%,56.1% of the control asexual sample respectively. This indicated that group Ⅰ、Ⅱare all better than the control asexual samples. Especially the first group (group Ⅰ) which includes sample No.44,No.48,No.54 and No.56 is the highest productivity category of the asexual family.

Abstract: This paper,according to the data of 69 asexual tung tree samples from the main tung origin areas all over the country,which are recorded continuously for 7 years in Jinhua experiemental site,completed the analysis of 12 factors including tree body,fruits and their economic value and their contributions by canonical correlation analysis method. The canonical correlations of comprehensive growth factors and comprehensive oil productivity factors are studied. Based on the canonical correlation value from the model of each sample,a sample distribution chart was created and all the samples are clustered as 4 groups.The oil percentages are 238.6% 187.7%,112.3%,56.1% of the control asexual sample respectively. This indicated that group Ⅰ、Ⅱare all better than the control asexual samples. Especially the first group (group Ⅰ) which includes sample No.44,No.48,No.54 and No.56 is the highest productivity category of the asexual family.
