영문 초록

In order to indentify linkage group of resistant gene(s) of rice variety IR50 bred at IRRI to Bacterial Blight, IR50 was crossed with five genetic marker lines and F₂ plants of these crosses were inoculated by the inoculum of Pathotype Ⅰ and Ⅲ, from maximum tillering stage to flowering stage. The resistance of IR50 to Pathotype Ⅰ and Ⅲ appeared to be controlled by different single dominant gene, respectively. These two genes were linked each other with recombination value of 1.0 - 13.1%, but they were independently segregated with all the marker genes tested, such as, C, lg, Ph⁺, g, gh, Lh, la, bc, and gl which located on the linkage group Ⅰ, Ⅱ, Ⅳ, Ⅵ, Ⅶ, Ⅷ, XI, and XII, respectively.
