Cassava is an important crop in the tropics. The Manihot genus had 98 species and no barriers for efficient reproductive isolation have been observed; therefore plant breeders have an immense gene pool to work with. Genes from wild species have already been successfully used to obtain var. resist...

La yuca es un cultivo importante en los tropicos. El genero Manihot tiene 98 especies y no se han observado barreras para el aislamiento eficiente con fines reproductivos; por tanto, los fitomejoradores tienen un inmenso acervo genico con que trabajar. Ya se han utilizado exitosamente genes de es...

The importance of estimating genetic parameters in cassava in order to produce superior performing cv. is highlighted. Different concepts related to phenotypic variance are discussed; variance is divided into genetic (additive, dominance, epistasis) and environmental. Of the former, additive vari...

Se destaca la importancia de la estimacion de los parametros geneticos en la yuca para producir cv. superiores. Se discuten diferentes conceptos relacionados con la varianza fenotipica, la cual se divide en genetica (genetica aditiva, dominancia, epistasis) y ambiental; de las anteriores, la vari...

In 1984, most of the pathology efforts of the CIAT Bean Program concentrated on the evaluation of bean germplasm for their reaction to the main bean pathogens under field conditions in several international nurseries throughout many of the bean growing areas. High priority was given to the most w...

En 1984, la mayoria de los esfuerzos en patologia del Programa de Frijol del CIAT se concentraron en la evaluacion del germoplasma de frijol por su reaccion a los principales patogenos del frijol en condiciones de campo en varios viveros internacionales en muchas de las areas de cultivo. Se dio a...

Insect pest and disease outbreaks are driven by the environmental factors, presence of susceptible crop plants, and insect pest or pathogen population. Future climate variability and climate change (CC) are expected to modify the distribution and severity of pest damage and disease epidemics. In ...
