Analysis of genetic diversity of leaf phenotypes in Chinese jujube germplasm
【Objective】This study aims to reveal the phenotypic diversity of leaf traits in jujube germplasm resources, providing a theoretical basis for the introduction, evaluation and utilization of superior germplasm.【Method】Thirteen leaf phenotypic traits were measured in 247 jujube germplasm accessions. Descriptive statistics, correlation analysis, Shannon-Wiener diversity index (H'), principal component analysis (PCA), and Ward’s method-based hierarchical clustering analysis was employed to investigate the variation patterns of leaf phenotypes.【Result】The leaf phenotypic traits of the tested jujube germplasm exhibited substantial variation, with petiole length showing the highest coefficient of variation. The Shannon-Wiener diversity index (H') ranged from 1.67 to 2.08, indicating rich genetic diversity. Correlation analysis revealed that leaf length was significantly positively correlated (P < 0.01) with leaf width, petiole length, leaf area, and leaf perimeter, while it was significantly negatively correlated (P < 0.05) with leaf angle. PCA extracted four principal components, with a cumulative comtribution rate of 83.19%, among which leaf perimeter, chroma (c*), leaf length-to-width ratio, and lightness (L*). Cluster analysis (Ward’s method) classified the germplasm into six major groups: long-petiole large-angle type, large-leaf-area type, short-petiole small-leaf type, small-leaf yellowish type (low L*, high b*), low-hue-angle type (low h*), and broad-leaf dark-green type (high c*, low h*).【Conclusion】The 247 jujube germplasm accessions exhibited extensive phenotypic variation and high genetic diversity. The leaf length-to-width ratio, leaf perimeter, chroma, and lightness can serve as core indicators for evaluating jujube germplasm resources. The integrated diversity analysis and clustering results provide critical insights for germplasm assessment. This study establishes a theoretical foundation for the introduction, domestication, genetic ideutification and evaluation, and innovation of jujube germplasm.
