Genetic Study of Aromatic Rice Through Molecular Markers

By Zilhas Ahmed Jewel

For selection of aromatic rice lines 26 rice genotypes were used to evaluate agronomic characteristics, aroma detection through sensory test and genotypic analysis using SSR markers.Aroma was detected by 1.7% KOH as a sensory test. Six, seven and ten rice genotypes respectively strong aroma, moderate aroma, slight aroma and three no aroma.Three SSR primers RM223, RM515, RM342 were used for identifying fgr gene locus in 26 rice genotypes. Primer RM223 identified the fgr locus as homozygous condition 6strong aromatic,7moderate aromatic,10 slight aromatic & the rest3 non aromatic. Primer RM515 detected 4strong aromatic,6 moderate aromatic,16 as slight to non aromatic.The primer RM342 detected 3 strong aromatic,4 moderate aromatic,19slight aromatic.Compare among markers, ?RM223 detected the highest number of fgr locus in aromatic rice genotypes.Finally, it can be said that among primers, RM223 responded best in all the 26 rice genotypes because RM223 primer could be able to identify aromatic and non-aromatic genes having higher yield with good agronomic performance and other grain quality traits.These elite lines could be readily used in breeding program for release aromatic rice variety
