Abstract

In the fields of agricultural, food and medical research, the potential impacts of tea on human health are of special interest because tea (Camellia sinensis (L.) Kuntze) is continuously consumed by many people in the world. The evaluation of the diversity of genotypes found in tea germplasm can aid in the improvement of the breeding programme. In this study, the genetic diversity of 30 tea genotypes from two commercial sites of tea production in Iran was investigated by using morphological and 12 ISSR markers. Morphological analysis showed that the diversity between samples of tea was limited, and the narrow matching range was calculated. In cluster analysis at level 0.63, samples were divided into four groups. The application of 12 ISSR primers produced 91 polymorphic bands. PIC test showed a range of 0.41–0.48. Based on the ISSR data, the matching range was obtained in the range of 0.24–0.93. In cluster analysis, samples at level 0.58 were divided into five groups. According to the results, it can be understood that these series of traits and primers can very well recognize genetic differences. Using these markers, genetic diversity was observed among tea genotypes, but this diversity was not such as to be able to separate genotypes of various regions from each other. The results showed that the tea genotypes in Iran had high genetic diversity. As a consequence, the findings of our study will help the development of tea germplasm conservation strategies and their sustainable use in breeding programmes.

茶(Camellia sinensis (L.))遗传资源多样性位于里海南部地区的Kuntze)

在农业、食品和医学研究领域，茶对人体健康的潜在影响引起了人们的特别关注，因为茶(Camellia sinensis (L.))Kuntze)被世界上许多人不断消费。对茶叶种质中发现的基因型多样性进行评价有助于改进育种计划。本研究利用形态标记和12个ISSR标记，对伊朗两个茶叶产地的30个茶叶基因型的遗传多样性进行了研究。形态学分析表明，茶叶样品之间的差异有限，计算出了较窄的匹配范围。在0.63水平的聚类分析中，将样本分为四组。12条ISSR引物的应用产生了91条多态性条带。PIC检验范围为0.41-0.48。基于ISSR数据，得到的匹配范围为0.24 ~ 0.93。在聚类分析中，水平为0.58的样本分为5组。由此可见，这一系列性状和引物能够很好地识别遗传差异。利用这些标记，可以观察到茶叶基因型之间的遗传多样性，但这种多样性不足以区分不同区域的基因型。结果表明，伊朗茶叶基因型具有较高的遗传多样性。因此，我们的研究结果将有助于茶叶种质资源保护策略的制定及其在育种计划中的可持续利用。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
