Several physical and biological factors that limit cassava productivity are described: temp. and photoperiod, soil water availability, RH, soil characteristics (fertility and pH), and pests and diseases. Six edapho--climatic zones (ECZ) for cassava production are defined on the basis of temp.: lo...

Taller Latinoamericano sobre Intercambio de Germoplasma de Papa y Yuca (1, 1982, Cali, Colombia). Memorias
Se revisan los avances en el mejoramiento de la yuca durante una decada hasta 1985 por CIAT y el International Institute of Tropical Agriculture (Nigeria). Los temas tratados cubren recursos de germoplasma en el genero Manihot; citogenetica en Manihot spp.; coleccion y conservacion de germoplasma...

Pre-breeding : an alternative to add value to the plant genetic resources
Cassava breeders and scientists in related fields from the 3 major cassava-producing continents (America, Africa, and Asia) were brought together for the lst time to discuss the latest advances in cassava breeding research and exchange ideas on future priorities. Most breeding programs now orient...

In large ex situ germplasm collections, such as that maintained at CIAT for cassava, it is common to observe duplicates. The presence of duplicate clones increases the cost of conservation without contributing to representation or the available genetic base for crop improvement. To identify group...
