DNA marker based evaluation of aromatic rice genotypes of Chhattisgarh region

Abstract

Among different strategies to detect aroma in rice, fragrance linked –DNA markers have potential to improve the efficiency and precision being simple, inexpensive and co-localized with aroma gene. In this study the F2 plants of two mapping population developed by crossing aromatic parent Tarunbhog with local non aromatic variety safri17 and aromatic variety Dubraj were evaluated for a set of 13 yield attributing traits and further, we evaluated the discrimination ability of 29 gene tagged functional DNA marker for genotypic selection of aromatic plants. All the F2 plants were categorized into two additional categories indicated involvements of more than two gene .out of 29 markers 2 were showed polymorphism.
