| 摘 要： | 【目的】研究现有番茄种质资源生长特性。【方法】以不同生态区引进的15份番茄种质资源为材料,对其在不同生育时期农艺性状、部分外观品质及果实性状等31个性状进行测定,运用主成分分析、相关性分析和聚类分析等方法综合评价在新疆的表现。【结果】31个性状可简化为6个主成分,分别为果实外观、叶片性状、产量因子、品质因子等,累积贡献率达到87.9%;利用欧式距离、类平均法将供试材料分为3个类群,第I类群包括7个品种;第II类群包括6个品种;第III类群包括2个品种(丽妃2号和香妃3号)。【结论】第I类群株高较矮,心室多,单株产量较高。该品种株高适中,茎秆粗壮,单果重大,横径和纵径大,叶长和叶宽较大、单株产量高,该类型品种整体表现较好;第四类群单株产量和单果重较低,株高较大、叶片数多,果梗洼小,可溶性固形物含量高,没有果面棱沟、果面茸毛和裂口,该类型品种外观品质较好。

| Abstract: | 【Objective】 To fully explore the growth characteristics of existing tomato germplasm resources. 【Methods】 15 tomato germplasm resources introduced from different ecological regions were used as materials to determine 31 traits including agronomic traits, some appearance quality and fruit traits in different fertility periods, and their performance in Xinjiang was comprehensively evaluated using principal component analysis, correlation analysis and cluster analysis. 【Results】 The results showed that the 31 traits could be simplified into 6 principal components, which were fruit appearance, leaf traits, yield factor, quality factor, etc. The cumulative contribution rate reached 87.9%; the test materials were divided into 3 taxa by using Euclidean distance and class average method, and taxon I included 7 varieties, which had shorter plant height, more ventricles and higher yield per plant. Taxon II consisted of 6 varieties, which had moderate height, stout stalks, large single fruit weight, large transverse and longitudinal diameters, large leaf length and width, and high single plant yield, and the overall performance of this type of varieties was good. The varieties of this type had better appearance and quality. 【Conclusion】 |
