Cassava is one of the main carbohydrate sources in the tropics, and it has worldwide importance as basic food for millions of persons in America and Africa. This root crop is affected by cassava frog skin disease that in Colombia produces yield losses of almost 90%. A phytoplasma was associated w...

The application of biotechnology tools has made it possible to make significant advances in the detection of pathogens and in the study of the genetic variability of pathogen populations. As a result, adequate disease management strategies can be planned, and disease resistance markers for plants...

Se evaluó la resistencia de los padres y las progenies de la familia de yuca K (M Nga 2 x CM 2177-2), a Phytophthora tropicalis. Además de los parentales se inocularon raíces frescas de 69 individuos de la familia K. Con la evaluación fenotípica y con base en las mapas moleculares de M Nga 2 (Mad...

Cassava frogskin disease (CFSD) is an economically important root disease of cassava (Manihot esculenta) in Colombia and other South American countries, including Brazil, Venezuela, Peru, Costa Rica, and Panama. The roots of severely affected plants are thin, making them unsuitable for consumptio...
