| description | Main activities carried out regarding plant breeding in Latin America, Africa, and Asia are summarized. In the case of Latin America, activities involved germplasm management, gene pool development, a project for developing semiarid and subtropical germplasm, participatory research for var. selection, and true cassava seed. For Africa, these included germplasm exchange and evaluation of introduced germplasm in Nigeria (CAMD, CBB); for Asia, these were national program development, technical developments, germplasm distribution, and var. release. Major research highlights are the introduction of a 1st lot of 87,615 botanical seeds obtained at CIAT headquarters by controlled hybridization to the International Institute of Tropical Agriculture as part of a collaborative agreement on cassava germplasm improvement in Africa. Half of these seeds were sown in 3 different ecologies of Nigeria, representing humid, subhumid, and semiarid areas of Africa. The material will be evaluated and selected on the basis of yield, growth habit, and reaction to biotic constraints, particularly CAMV and CBB. Likewise, the methodology developed for farmers' participation in var. selection on Colombia's northern coast has directly resulted in the release of 2 clones, ICA Catumare and ICA Cebucan. (CIAT) |

(CIAT) Se resumen las principales actividades relacionadas con el mejoramiento de la yuca en America Latina, Africa y Asia. En el caso de America Latina, las actividades incluyeron el manejo del germoplasma, el desarrollo de bancos de genes, un proyecto para desarrollar germplasma para regiones semiaridas y subtropicales, investigacion participativa para la seleccion var. y semilla verdadera de yuca. Para Africa, estas incluyeron el intercambio de germoplasma y la evaluacion de germoplasma introducido en Nigeria y para Asia, el desarrollo de programas nacionales, desarrollo tecnico, distribucion de germoplasma y liberacion var. Las actividades mas destacadas fueron la introduccion de un primer lote de 87,615 semillas botanicas obtenidas de la sede del CIAT mediante hibridacion controlada al International Institute of Tropical Agriculture como parte de un acuerdo colaborativo sobre el mejoramiento de germoplasma de yuca en Africa. La mitad de estas semillas se sembraron en 3 ecologias diferentes de Nigeria, las cuales representaban las areas humedas, subhumedas y semiaridas de Africa. Este material se evaluara y se seleccionara con base en el rendimiento, el habito de crecimiento y la reaccion a limitaciones bioticas, especialmente CAMV y CBB. Igualmente, la metodologia desarrollada para la participacion de los agricultores en la seleccion var. en la Costa Norte de Colombia ha originado la liberacion de 2 clones, ICA Catumare y ICA Cebucan.
