dc.description.abstractThe Indian sub-continent is home to a large number of indigenous aromatic landraces, which may serve as valuable genetic resources for future quality rice improvement to meet the ever growing demand for quality rice. In the era of high yielding modern varieties there is an urgent need to conserve and mainstream in production systems the valuable aromatic landraces occurring in traditional subsistence farming areas across the country. Understanding the population structure and adaptive variations of landraces is considered useful in this regard. In order to explore the genetic structure and diversity, 256 individuals of 8 aromatic landrace populations from four eco-geographic regions were genotyped using 17 SSR markers in the present study. Sixty-nine alleles were recorded and none of them were found common across all landraces. Twenty-six alleles were found unique to an individual landrace population. Kala Joha from Assam was most diverse in terms of effective number of alleles, expected heterozygosity and Shannon’s information index. Analysis of molecular variance (AMOVA) revealed maximum variation of 39.36% among populations within groups followed by among groups (30.52%) and the rest (30.12%) within populations.en_US
