Article Synopsis
- Genetic variations in 179 rice accessions from Cambodia were analyzed based on heading dates, chromosome components, and resistance to blast disease.
- Dominant accessions showed early heading in the North East region, medium heading in Central, and late heading in the South East along the Mekong River, while greater variation was found around Tonle Sap Lake.
- Accessions were classified into Japonica and Indica groups, with distinct resistance levels observed in different regions, and significant differences noted between those along the Mekong River and those near Tonle Sap Lake.
This study provides the first investigation of the physical traits, pasting properties and volatile compounds of Cambodian rice cultivars, including traditional, improved, and improved traditional varieties, allowing for their differentiation as high and low quality rice. Analysis of the grain quality traits illustrates interesting features of traditional varieties and correlations between traits that assist with understanding texture. Untargeted profiling of volatile compounds shows that high quality fragrant varieties not only contain 2-acetyl-1-pyrroline but also several other compounds, including aldehydes, alcohols and 2-alkylfurans that contribute to overall aroma.

They were examined using 12 SSR and two chloroplast markers to evaluate the degree of variation among populations and the genetic structure within populations. In the two annual populations, the number of plants with homozygous alleles at all 12 SSR loci were high (66.
