不同洋葱品种资源生物学特性评价及主成分分析
Biological Characteristics Evaluation and Principal Component Analysis of Different Onion Germplasm Resources
摘要
Abstract
[Objective] The purpose of this paper is to evaluate the characters of different onion varieties,analyze the diversity and specificity,and screen out the suitable varieties which can express good agronomic traits and have preferred specific traits for the local people.[Method] Field experiments about different onion varieties were carried out in Anningqu and Fukang respectively.Moreover,agronomic traits of the introduced different onion varieties were also investigated.Furthermore,the agronomic traits of different onion varieties were analyzed via principal component analysis and correlation analysis.[Result]The results showed that Jinqiu-white,Chunyuan-red,Lufeng-white and Xiyanghong-white had good performance on biological characteristics and high yield among all the various characters,except the variety Yuyuan-red and Jinqiu-red.According to the results of correlation analysis,a significant correlation existed among the single bulb weight,the yield,the vertical diameter of the bulb and the bulb diameter.The leaf number was significantly correlated with stem diameter and the number of fleshy scales.The leaf length also had a significant correlation with plant height,width and leaf diameter.A negative significant correlation of wax powder between disc stem diameter and thick fleshy scales was also found.[Conclusion] Jinqiu-white,Chunyuan-red,Lufeng-white,Xiyanghong-white can be used as excellent germplasm resources for native onion varieties cultivar improvement.关键词
