To understand the genetic diversity and indica-japonica differentiation in Bangladesh rice varieties, a total of 151 accessions of rice varieties mostly Bangladesh traditional varieties including Aus, Boro, broadcast Aman, transplant Aman and Rayada varietal groups were genotyped using 47 rice nuclear SSRs. As a result, three distinct groups were detected by cluster analysis, corresponding to indica, Aus and japonica rice. Among deepwater rice varieties analyzed some having particular morphological features that mainly corresponded to the japonica varietal group. Some small seeded and aromatic varieties from Bangladesh also corresponded to the japonica varietal group. This research for the first time establishes that the japonica varietal group is a prominent component of traditional varieties in Bangladesh, particularly in deepwater areas.
为了了解孟加拉国水稻品种的遗传多样性和籼粳分化，利用 47 个水稻核 SSR 对 151 个水稻品种进行了基因分型，这些品种主要是孟加拉国的传统品种，包括 Aus、Boro、broadcast Aman、transplant Aman 和 Rayada 品种群。聚类分析结果表明，共检测到三个不同的群体，分别对应于籼稻、Aus 和粳稻。在所分析的深水稻品种中，一些具有特殊形态特征的品种主要对应于粳稻品种群。孟加拉国的一些小粒和芳香品种也对应于粳稻品种群。本研究首次证实，粳稻品种群是孟加拉国传统品种的一个重要组成部分，特别是在深水地区。
