The Bean Team Nursery (VEF) is the 1st uniform and multidisciplinary evaluation for adaptation and disease and insect resistance and is composed of advanced, coded CIAT hybrid lines from various breeding projects, the germplasm bank, and national programs. Among the bush bean entries, 16 percent ...

La primera evaluacion multidisciplinaria y uniforme que se hacede los materiales por su adaptacion y resistencia a enfermedades yplagas es en el vivero del equipo de frijol (VEF) el cual secompone de lineas hibridas avanzadas, codificadas por el CIAT,procedentes de varios proyectos de mejoramient...

The factors affecting the quality of cassava roots were studied: var. and age of the plant; DM, starch, and sugar contents in the roots; cyanide contents in leaves and roots. Roots of bitter var. CMC-84 showed higher DM contents than those of sweet var. CMC- 40. Total and reducing sugar contents ...

Se estudiaron los factores que afectan la calidad de las raices como: var.; edad de la planta; contenidos de MS, almidon y azucares en la raiz; y contenidos de cianuro en hojas y raices. Las raices de la var. amarga CMC-84 presentaron mayor contenido de MS que la var. dulce CMC-40. Los contenidos...

The seventh testing cycle for promising CIAT selections under improved, low-input technology was completed in 1981 at 9 locations in Colombia. The overall av. yield of the trials was 8.5 t/ha/yr, which is nearly 3 times the national av. yield of 3-3.5 t/ha. Av. yield of local cv. was about twice ...

Research activities carried out by CIAT in collaboration with national research institutions for the improvement of bean production in the Central American and Caribbean region are analyzed. In 1981, preliminary trials (EP) were planted in Costa Rica and Guatemala in an effort to identify promisi...

Advances in research of the soil and plant nutrition section of CIAT's Cassava Program in 1981 are given regarding symptoms of Ca and S deficiency, germplasm screening for adaptation to high acidity and/or low P; effect of fertilization (long-term fertility); level and time of K application; effe...

Different aspects related to deterioration, treatments to extend cassava root durability, and root storage practices are briefly reviewed. The initiation and subsequent level of deterioration of cassava roots is closely related to the presence of mechanical damage which is normally caused at harv...

Se revisan brevemente los diferentes aspectos relacionados con la deterioracion, los tratamientos para extender la durabilidad de las raices de yuca y las practicas de almacenamiento de las mismas. El inicio y el grado posterior de deterioracion de las raices esta estrechamente relacionado con la...
