华东覆盆子优势种质资源的筛选与评价
Selection and evaluation of superior germplasm resources of Rubus chingii Hu
摘要
Abstract
In order to screen out the advantageous germplasm resources suitable for the breeding of new varieties,the main agronomic traits and chemical components contents of 20 germplasm resources of Rubus chingii Hu in Zhejiang Province were counted and determined.Diversity analysis,correlation analysis,principal component analysis and cluster analysis were carried out.The results revealed significant variability and rich diversity in both agronomic traits and chemical composition contents among the 20 R.chingii samples.Correlation analysis between agronomic traits and chemical composition contents indicated significant positive correlations between traits such as fruit pedicel length,fruit shape,and contents of most chemical components.Positive correlations were also observed between traits like fruit yield,flower diameter,stem branching number,and contents of certain chemical components,while negative correla-tions were found between traits such as plant diameter,branch diameter,and contents of specific chemical compo-nents.Based on the principal component analysis scores for fruit yield and chemical composition contents of R.chin-gii,two superior germplasm resources,namely Y3 and Y9,were identified.This study provides valuable insights for the breeding of new R.chingii varieties and the evaluation of medicinal quality in authentic medicinal materials.关键词
