Molecular characterization of short grain aromatic rice landraces of Odisha for detection of aroma

Sensory method along with four molecular markers (ESP, EAP, INSP and IFAP) were used for evaluation of aroma in indigenous short grain aromatic rice genotypes collected from different regions of Odisha (India). Sensory method of aroma evaluation from kernel sample of these genotypes could detect mild, moderate and strong aroma in 8, 36 and 26 genotypes, respectively. The molecular level aroma detection could identify homozygous fragrance in 59 genotypes, whereas 11 genotypes were found to be with heterozygous nature for this locus indicating requirement of more efforts towards understanding their genetic base of aroma. Integration of sensory method and molecular level evaluation of aroma could help in rapid identification of aromatic genotypes within a large population.
