Abstract

Aromatic rice has become popular owing to its aroma. Growing demand for aromatic rice has spurred interest of breeders. In this study, twenty five BC1F1 rice lines of backcross hybrid combinations were used to evaluate aromatic characteristics through sensory test and  using microsatellite markers. There are twelve lines had aroma and one no aroma were chosen though sensory test.  Allele Specific Amplification with four primers (External Antisense Primer, External Sense Primer, Internal Non-fragrant Sense  Primer, and Internal Fragrant Antisense Primer) were used for identifying fgr gene locus in 25 rice lines. Analysis of PCR results showed that BC1F1 population segregated into 1:1 ratio (homozygous fragrant: heterozygous non-fragrant). Thus, twelve promising lines were identified with homozygous fragrant genotype.
Keywords: Aromatic rice, microsatellite markers, sensory test
