Resumo: EMBRAPA-CNPAF began to explore the prospects for and problems of hybrid rice in 1984 via two areas: the introduction of allogamic traits to develop A and B lines and reciprocal recurrent selection. The methodological steps involve identifying maintainer and restorer lines, introducing allogamic traits into maintainer lines, and transferring the cytoplasmic genetic male sterility system to derived F 4 maintainer lines. Development of line 0461 with allogamic traits and good agronomic behavior and several hybrids is the most significant result. Future plans are directed toward developing an economically viable methodology to produce hybrid seeds, locating partners in the private sector, identifying new cytoplasm sources to produce genetically diverse A lines, and evaluating the economic need to use the allogamic traits
