Abstract
Fragrance is one of the most important trait in cultivated rice. The fragrant allele in rice germplasm worldwide was investigated continuously. The purpose of this study was to investigate variation in non-coding sequences of the fragrance (fgr) gene in cultivated rice and its relatives from Indochina (Thailand, Laos and Cambodia) using PCR and re-sequencing techniques. Two new additional insertion/deletion were observed in intron 6 of the fgr gene in fragrant cultivated rice and its relatives from Thailand compared to fragrant and non-fragrant cultivated rice accessions from Myanmar, China and Japan. This finding may shed light on a wide range of genetic resources of rice available for aroma trait in breeding program and on the evolutionary process underlying differentiation of rice cultivars from progenitor lineage.
