Abstract

We demonstrated that the segregation ratio of avirulence and virulence traits on rice cultivars, Hattan 3 and line K59-1, and the mating types of parasexual recombinants were consistent with those of sexual progeny in the rice blast fungus Magnaporthe oryzae. Our results indicated that the genetic characters of parasexual recombinants segregated in a recombination manner similar to sexual events.
