| Abstract: | Deduction of blast-resistant genes of 211 rice varieties collected from Jiangxi in 2009 was conducted by in vitro inoculation of rice leave segments,using 22 rice blast(Magnaporthe oryzae) differential isolates.18 resistant genes were deduced in the 211 rice varieties,of 18genes,the appearance frequencies of 9 genes i.e.Pi-sh,Pi-km,Pi-ta2,Pi-9,Pi-5,Pi-z,Pi-3,Pi-1,Pi-kh,were above 5%,of them,the Pi-kh was of the highest appearance frequency of 62.09%.those of 9 genes i.e.Pi-ta,Pi-kp,Pi-12,Pi-zt,Pi-b,Pi-7,Pi-... |
