Background
Genetic diversity and population structure of cultivated
rice (Oryza sativa L.) have been studied worldwide
(Garris et al. 2005; Yu et al., 2003; Zhao et al. 2010;
Ali et al. 2011; Chen et al., 2011). However, only few
Thai rice germplasm has been included in these studies
(Garris et al. 2005; Yu et al., 2003), and to our knowledge,
there is no report on genetic structure of Thai
