Molecular and morphological characterization of aromatic farmer’s rice varieties collected from different districts of Madhya pradesh, India

In the present study, sixty four aromatic landraces of rice collected from different districts of Madhya Pradesh were analysed for genetic variation using SSR markers. Specially, the objective of the study was DNA fingerprinting and genetic diversity analysis of aromatic landraces to requisite to study the unique feature and to identify the duplication among them and to assist in broadening the germplasm base of future aromatic rice breeding programs. Very high variation was observed for the trait sterile lemma colour in the classes of straw (76.56%), purple (10.94%), gold (7.81%) and 4.69%). Similar trend was also observed for grain weight of 1000 fully developed grains in the classes of low (28.13%), medium (25.00%), very high (20.31%), very low (18.75%) and high (7.81). The experiment for analysing genetic relationship using 31 SSR primers revealed that all primers showed polymorphism with reproducible and informative profiles. The DNA amplification pattern revealed that a total number of 594 SSR loci were amplified with an average of 19.31 loci per primer. | Molecular and morphological characterization of aromatic farmer’s rice varieties collected from different districts of Madhya pradesh, India
