Morphological & Molecular Characterization Of Aromatic Rice

The present book was conducted in the Department of Genetics and Plant Breeding, Indira Gandhi Krishi Viswavidyalaya, Raipur (C.G.) during kharif 2011 with the objectives to study the morphological and molecular characterization of aromatic rice landraces at various growth stages. The experimental material consisted of thirty eight aromatic landraces, studied for 47 diagnostic morphological traits and nineteen SSR markers. Variability for morphological traits was recorded for all diagnostic traits and for each land races a passport information for all traits were developed. All considered morphological descriptors showed markeable differences in their distribution and amount of variations within them. The analysis of variance indicated existence of considerable amount of variability for all observed characters. The high amount of genotypic and phenotypic coefficient of variation with high genetic advance as percentage of mean was observed for grain yield, number of grains/panicle, 1000 seed weight and number of panicles/plant. In the present study the genetic similarity of these landraces was also worked out at molecular level for 13 loci.
