La evolución de las especies que describiera Charles Darwin se basa en dos elementos: la ocurrencia de variabilidad genética y una selección que favorece que individuos genéticamente superiores tengan mayor probabilidad de producir progenie. El mejoramiento genético de los cultivos se base en eso...
En este módulo se ilustra la manera en que los tallos de yuca (material de siembra) se almacenan debajo de un árbol desde el momento de su cosecha hasta que llega el momento de su utilización para iniciar un nuevo ciclo de cultivo. Se muestra también los cangres o estacas obtenidos de cada tallo ...
Knowledge on the reproductive biology of cassava, relevant to breeders and molecular geneticists, is still limited. Therefore, different studies were carried out to determine the duration of stigma receptivity and the rate of pollen tube growth. Inflorescences were covered for up to 3 days after ...
Although numerous studies of diversity have been conducted in cassava, there is no comprehensive assessment of global genetic diversity. Here we draw on previous studies and breeders’ knowledge to select diversity sets from the International Institute of Tropical Agriculture (IITA) and the Intern...

A global overview of cassava genetic diversity
The increasing demand for cassava (Manihot esculenta Crantz) for food and non-food uses in the tropics necessitates that its breeding for increased root productivity be made faster. The characteristic long breeding cycle and heterozygous nature of this crop, pose a major obstacle to its rapid gen...
