摘要: 【目的】研究不同辣椒资源各调查性状间的相关性和聚类分群,为适宜新疆制干辣椒品种选育步改良奠定一定的基础。【方法】以24份辣椒高代自交系为材料,通过果实主要性状、果肉细胞主要结构特征和损耗75%水分需要的耗时调查,对所调查性状进行相关性和聚类分析。【结果】各调查性状间存在不同程度的显著或极显著正负相关,相关系数介于-0.625**~0.976**。利用欧式距离,类平均法可将24份辣椒资源分为五大类,第Ⅰ大类包含8份材料,第Ⅱ大类包含6份,第Ⅲ大类包含3份,第Ⅳ大类均仅包含6份材料,第Ⅴ大类仅包含1份材料,这份材料具独特性。【结论】辣椒遗传多样性丰富,沥干时间(损耗75%水分需要的耗时)仅与腔室面积占比存在显著负相关。

Abstract: 【Objective】 The aim of this paper is to study the correlation and cluster of different characters in different pepper resources and lay a foundation for the further improvement of Xinjiang dry pepper varieties.【Method】The 24 pepper advanced self-line germplasm resources were employed in this paper to evaluate the main fruit's traits, the main characteristic of the pulp cells structure and the time-consuming of the fruit losing 75% water. Thereafter, the correlation and cluster analysis was implemented to the entire characteristic. 【Result】The results showed that the positive and negative significance correlation existed among the characteristics, and the correlation coefficient ranged from -0.625** to 0.976**. Furthermore, 24 pepper germplasm resources were divided into five groups by euclidean distance UPGMA method. The first group included 8 lines, the second group included six lines, the third group included three lines, the fourth group included six lines, and the fifth group only included one line which implied the peculiarity of this line.【Conclusion】Pepper is rich in genetic diversity. The draining time (time required for 75% water loss) was only negatively correlated with the proportion of the chamber area.
