Abstract

Piriculariosis (Blast disease) is the main phytopathologic problem that causes low rice yields in Cuba. For this reason, three P. grisea haplotypes isolated in Cuba from rice plants in two production areas, were evaluated in controlled conditions and with artificial inoculation. Later they were used in breeding rice varieties to blast resistant. The obtained results suggest the selection of haplotypes A 18 and B 6 for rice varieties evaluation under control conditions and, in this way, two lineages of blast are represented, as well as the broadly distributed and aggressive lineage. Seven resistant lines to the evaluated haplotypes were selected. They constitute an important germoplasm basement to obtain resistant rice varieties.
