Rice germplasms collected from different regions could be used as valuable resources for the future breeding programme. For the utilization of such collections, knowledge about the level and distribution of genetic diversity among these collections will facilitate the breeder. In this study, we report the phenotypic correlation, biochemical quality parameters and population genetic analysis of 35 rice accessions including 34 aromatic rice from different countries and a nonaromatic, Nagina 22, a well-known drought resistance variety. Further biochemical quality analysis, gel consistency test, molecular diversity analysis with 55 simple sequence repeat markers, population structure analysis and pair wise FST analysis were also conducted to assess the genetic diversity. The collected rice genotypes showed significant variability in different agronomic traits, i.e. spikelet per panicle, branches per panicle etc. Results obtained from the above tests demonstrated the importance of regional genetic studies for understanding the diversification of aromatic rice in Asian and African rice.

亚洲和非洲芳香稻（Oryza sativa L.）基因型的遗传多样性和种群结构分析。

从不同地区收集的水稻种质可以用作未来育种计划的宝贵资源。为了利用这些收藏品，有关这些收藏品中遗传多样性的水平和分布的知识将为育种者提供便利。在这项研究中，我们报告了35种水稻的表型相关性，生化质量参数和群体遗传分析，其中包括来自不同国家的34种香米和一种非芳香性的Nagina 22（一种著名的抗旱品种）。还进行了进一步的生化质量分析，凝胶一致性测试，具有55个简单序列重复标记的分子多样性分析，种群结构分析和成对FST分析，以评估遗传多样性。
