摘要

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.
