This paper compares selection efficiency for high palatability breeding lines using marker-assisted selection andconventional selection methods in rice. A total 4 cross combinations of japonica cultivars were selected using marker-assistedselection with a set of 13 DNA markers associated with grain quality and conventional selection methods in F3 and F5 generationsassessing palatability using the Toyo taste meter. The multiple regression value with a set of 13 DNA markers was utilized asthe marker-assisted selection index. The number of polymorphic markers among 13 DNA markers ranged from 3 to 7 betweenthe parental cultivars. Among these cross combinations, there was no significant difference between marker-assisted selection andconventional selection methods for selection of lines with high palatability. This demonstrates that marker-assisted selection bymarker-based regression value might not be a good method for selection to apply the all breeding populations for high palatabilityline selection. While each method allowed equally effective selection of high palatability lines, the regression analysis usingpolymorphic markers will need to be re-calculated for each cross combination.
