Specific patterns of genetic diversity among aromatic rice varieties in Myanmar.

ABSTRACT:

Background

After observing peculiar rice varieties in Myanmar, in terms of classification in varietal groups and of grain quality, we focused on Myanmar varieties and analyzed variations at 19 microsatellite loci as well as sequences of the aroma gene BADH2.

Results

Microsatellites were able to retrieve the well-established classification into Indica (isozyme group 1), Japonica (group 6, comprising temperate and tropical forms) and specific groups from the Himalayan foothills including some Aus varieties (group 2) and some aromatic varieties (group 5). They revealed a new cluster of accessions close to, but distinct from, non-Myanmar varieties in group 5. With reference to earlier terminology, we propose to distinguish a group "5A" including group 5 varieties from the Indian
