영문 초록

The blast resistant semi-dwarf rice breeding lines IR1905-81-3-1, IR9669-PP8361-1, IR5533-PP854-1 and IR3273-289-2-1473 were crossed to a susceptible cultivar 55061. The four resistant parents were crossed diallelly for testing allelism relations of resistance to blast. The F₂ populations of the above crosses and two hundred F₃ lines of the cross 55061/IR1905-81-3-1 were screened against the races of Pyricularia oryzae IA-61, IB-47, IC-27, IH-1 and II-1. The blast resistant rice line IR1905-81-3-1 appeared to convey three dominant resistance genes, and IR9669-PP836-1, IR5533-PP8541 and IR3273-289-21473 to carry two or more dominant resistance genes respectively. The four resistant lines tested were proved to carry at least one common resistance gene.
