Blast disease of rice (Oryza sativa) caused by M. grisea (anamorph=Pyricularia grisea) is one of the principal disease of rice. Our present observation regarding the genetics of fertility and host range in M. grisea indicates that the isolates from Foxtail millet (Setaria italica) are highly compatible and hermaphrodite, and mated with most of the field isolates tested. High compatibility and fertility was observed in non-rice isolates but was low in non-rice x rice crosses.
