Abstract
A single dominant blast resistance gene was identified in Chinese indica rice (Oryza sativa) cv. Guangchangzhan (GCZ), which shows complete resistance to Japanese isolate Ken53-33 of Magnaporthe grisea. Genetic analysis of the backcross (BC1) and second-generation (F2) populations from a cross between susceptible cv. Lijiangxintuanheigu (LTH) and GCZ indicated that the resistance was conferred by one dominant gene. This gene was mapped on the long arm of chromosome 2 and flanked by RM166 and RM208 at distances of 4.00 ± 4.90 and 6.30 ± 4.89 cM (centiMorgans), respectively. It was designated tentatively as Pi-g(t).
