초록

Rice stripe disease, caused by rice stripe virus (RSV), is one of the major virus diseases in East Asia. This study was conducted to identify new resistance genetic source to Rice stripe disease. Genetic diversity of 155 rice cultivars was evaluated using 9 co-dominant InDel markers and 1 STS marker, ST10, near Stv-bi allele. These cultivars were classified into two groups by cluster analysis based on Nei’s genetic distances. In comparison of bioassay for RSV resistance and genotyping using SSR markers showed that recombination value of RSV resistance and InDel7 marker type was 3.8%. Some RSV resistant varieties including umarat, Pervomajszkij, and Tung Ting Wan Hien 1 showed susceptable allele type in InDel7 and ST-10marker. These results indicate those cultivars can be able to get the different gene resistance with Stv-bi gene. Further genetic studies on selected varieties in this study will be use for improving RSV resistance in japonica rice.
