Abstract

The present investigation was intended to assess the extent of genetic diversity present among the selected genotypes of Oryza sativa (including TGMS lines) using SSR markers. The SSR markers used for the study gave average Polymorphism Information Content (PIC) value of 0.551. The primer RM 9 followed by RM 536 has given maximum PIC value and the primer RM 29 gave the minimum. It was inferred that the primers RM 9 and RM 536 had been the better choices in this study. The lines, TS09 24 and TS09 26 were in the same cluster as they derived from the same parents. The TGMS lines TS 29 and TNAU 27S are in separate cluster from other parents indicating that these lines are highly diversified and their crosses can give improved cultivars. Bangladesh J.

利用 ssr 标记对有潜力的 tgms 品系和高结实率水稻品种进行分子表征和多样性分析

本研究旨在利用 SSR 标记评估所选野生稻基因型（包括 TGMS 品系）的遗传多样性程度。研究中使用的 SSR 标记的平均多态性信息含量（PIC）值为 0.551。引物 RM 9 和 RM 536 的 PIC 值最大，引物 RM 29 的 PIC 值最小。由此推断，在本研究中，引物 RM 9 和 RM 536 是较好的选择。TS09 24 和 TS09 26 这两个品系属于同一群，因为它们来自同一个亲本。TGMS 品系 TS 29 和 TNAU 27S 与其他亲本分在不同的群中，这表明这些品系的多样性很高，它们的杂交可以培育出改良的栽培品种。孟加拉国植物学杂志52(4):1067-1070，2023 年（12 月）

期刊介绍： Bangladesh in situated on the north of Bay of Bengal. Climatically it is a humid subtropical country. Most of the land is deltaic plain of two great rivers, the Ganges and the Bhrammaputra and it tributaries. The country has rich diversity of plants. Main crops cultivated are Rice, Jute, Wheat, Maize, Sugarcane, Mustard and different kinds of Lentils. There are a good number of Public and Private Universities and Plant Research Establishments. Bangladesh Journal of Botany is the official organ of the Bangladesh Botanical Society established in 1972. Since 1972 Bangladesh Journal of Botany is being published regularly. Two issues of the Journal are published, one in June and another in December. Scientific papers (Full paper and short communication) on any field of Plant Sciences from anywhere in the World are considered for publication in Bangladesh Journal of Botany.
