초록
A total of 285 Korean rice cultivars were used for amylose content and genetic analyses using KASP markers related to the amylosecontent. We used three polymorphic KASP markers targeting the Waxy (Wx) gene and compared the genotyping efficiency with previouslyreported molecular markers. The rice cultivars were raised in Miryang, Korea, for one period. Genetic analysis of the rice cultivars revealedthat the three KASP markers on the Wx gene were functional for genomic selection of SNPs related to amylose content variation. Therefore,the three KASP markers targeting different Wx alleles can be used for genomic selection. In addition, KASP markers were more efficientthan previously reported molecular markers that target the same alleles. These findings can be beneficial for the breeding and genomic selectionof high-quality rice in Korea.
Abstract

Genetic analysis of the rice cultivars revealedthat the three KASP markers on the Wx gene were functional for genomic selection of SNPs related to amylose content variation. Therefore,the three KASP markers targeting different Wx alleles can be used for genomic selection. In addition, KASP markers were more efficientthan previously reported molecular markers that target the same alleles. These findings can be beneficial for the breeding and genomic selectionof high-quality rice in Korea.
