dc.descriptionHybrid rice has great prospects in Brazil. The first hybrid varieties are intended for release in irrigated areas, where 49% of Brazil’s rice is produced. The technological level of the farmers (which results in average yields of 4.8 t/ha), the good infrastructure for seed production and distribution, and the expected improvement in the economical productivity of hybrid rice provide a good basis for developing hybrid varieties. The National Research Center for Rice and Beans is developing a hybrid rice breeding program based on the three-line method, using the wild abortive cytoplasm and the long stigma trait transferred from O. longistaminata A. Chev. to improve cross fertilization. The first set of identified maintainer lines are being sterilized, the combining ability tests will be done soon, and hybrid rice varieties probably will be released in the next 5 yr. To improve the available variability for varietal creation in the future, a reciprocal recurrent selection scheme has been started.
