| Abstract: | The rice blast is one of the most serious diseases in rice production. Breeding for disease resistant varieties is the most effective and efficient method to reduce the disease damage. In this study, one rice candidate restorer line, R153, harboring the rice blast resistance gene Pi25 was selected through the approach of molecular marker-assisted selection using segregating population derived from cross between the Hui11-32 and BL108 （the donor of the blast resistance gene Pi25）. Tightly linked DNA marker Si13070C and functional marker CAP3/BglⅡ were used. The blast resistance identification was conducted in a rice blast disease hotspot location, Shanghang County, Fujian Province, China. R153 showed a good resistance to rice blast in the evaluation and provided a new resource for rice breeding. |
