Conventional and inter-specific crossbreeding of upland rice for the savannas ecosystem
Conventional crossbreeding has permitted the development and release of modem upland lines in Bolivia, Brazil and Colombia. Since 1996, no new conventional "Japonica" Oryza sativa crosses were made. Though, as we have advanced segregating lines in the pipeline, we continue their evaluation and multiplication in Colombia for future shipping to LAC NARS. The CIAT rice project now concentrate on broadening the genetic base of upland rice. Interspecific crosses between Oryza sativa and the African cultivated Oryza Glaberrima as well as with wild relative species is one of the new breeding strategies used to achieve the objective.
