DEVELOPMENT OF MOLECULAR MARKER FOR ASSESSMENT OF INTRASPECIFIC POLYMORPHISM OF RC GENE CONDITIONING RED PERICARP IN RICE ORYZA SATIVA L

Red rice is the worst field weed in all rice-cultivation areas. Early diagnosis of red rice in primary seed breeding program is an overriding task, which solution directly influences the quality of the rice seeds. Red and red-brown colors of pericarp are determined by two loci at least: Rc and Rd, expressing in conjunction with the Rc gene. In this study we have developed an intragenic codominant molecular marker for the Rc gene and tested it with contrasting as to the seed colour rice varieties examined feature. The efficacy of the marker has been shown for 1142 families of rice, each sample containing 120 plants.
