摘要:

为筛选出适宜新品种选育的华东覆盆子优势种质资源,统计和测定了20份浙江省的华东覆盆子种质资源主要农艺性状和化学成分含量,并进行多样性分析、相关性分析、主成分分析和聚类分析。结果显示,20份华东覆盆子农艺性状和化学成分含量的变异幅度较大,多样性丰富。华东覆盆子农艺性状与化学成分含量间的相关性表明,果梗长、果形与多数化学成分含量间呈显著正相关性;果产量、花径、茎分枝数与少数化学成分含量间呈正相关性;株径、枝径与少数化学成分含量间呈负相关性。基于华东覆盆子的果实产量和化学成分含量主成分分析得分,综合评价筛选出品质优良的2份资源,分别是Y3和Y9。研究结果为华东覆盆子新品种选育和道地药材品质评价提供了参考。

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 correlations were found between traits such as plant diameter, branch diameter, and contents of specific chemical components. Based on the principal component analysis scores for fruit yield and chemical composition contents of R. chingii, 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.
