Patil, Basavaprabhu LFauquet, Claude M.[Studies on differential behavior of cassava mosaic geminivirus DNA components, symptom recovery patterns, and their siRNA profiles]Studies on differential behavior of cassava mosaic geminivirus DNA components, symptom recovery patterns, and their siRNA profiles

A standard system for the evaluation of bean germplasm under field conditions is described, including a table with the developmental stages of the common bean plant which is used in the proposed system. This system has been tested in Colombia and many countries in Latin America, Africa, and other...


Schoonhoven, Aart vanPastor Corrales, Marcial A.[Standard system for the evaluation of bean germplasm]Standard system for the evaluation of bean germplasm

Methods used to identify BCMV are described in terms of symptomatology (common mosaic, black root); transmission (seed, insect, manual); responses of differential bean cv. (mosaic, systemic or local necrosis, local lesions, immunity); cytology (light and electron microscopy); purification and ser...

Nolt, Barry L.Pineda López, BenjamínVelasco, Ana Cecilia[Surveys of cassava plantations in Colombia for virus and virus- like diseases]Surveys of cassava plantations in Colombia for virus and virus- like diseases
Autor: Lozano, J.C.

The main pathological problems of the cassava crop are summarized. Four bacterial diseases have been identified and their causal agents characterized: CBB, angular leaf spot, bacterial stem rot, and bacterial stem gall. Two mycoplasmal problems, witches` broom and antholysis, have been identified...


Lozano, J.C.[Problemas patologicos en el cultivo de la yuca]Problemas patologicos en el cultivo de la yuca

Large quantities of cassava common mosaic virus (CCMV) were purified from systemically infected Nicotiana benthamiana plants. A polyclonal antiserum, with a titre of 1/128 in the tube precipitin test, was produced by immunising rabbits with purified virus. Viral antigens were detected in cassava,...


Nolt, Barry L.Velasco, Ana CeciliaPineda López, Benjamín[Improved purification procedure and some serological and physical properties of cassava common mosaic virus from South America]Improved purification procedure and some serological and physical properties of cassava common mosaic virus from South America

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...


Jennings, DLHershey, Clair H.[Cassava breeding: a decade of progress from international programmes]Cassava breeding: a decade of progress from international programmes

The creation of an advanced cassava research network, through the identification of key constraints in cassava production and processing that could be managed through a multidisciplinary, interrelated network approach, was discussed at this workshop. Priorities were set and potential projects tha...
