The role of integrated development projects in the planning of institutional activities in the agricultural sector is analyzed. CIAT's participation in the national integrated rural development program, DRI, with the cassava natural drying project for animal feed on Colombia's Atlantic Coast, is ...

Se analiza el papel de los proyectos de desarrollo integrado en la planificación de actividades institucionales en el sector agricola. Se revisa la participación de CIAT en el programa nacional de desarrollo rural integrado, DRI, con el proyecto de secado natural de la yuca para alimentación anim...

The objectives of the Myanmar scoping study are: To collect, collate and analyse existing secondary information on RTC area, production, processing, marketing, and consumption at the national and state/district levels where (a) RTC (root and tuber crops) production/consumption is most important a...

Since 1990 we have undertaken a large number of experiments and conducted research on the development and use of cassava roots and leaves as animal feed resources, in order to explore the possibility of substituting cassava-based feeds for those of grain, thus saving grain for human consumption t...

Results of research carried out at El Carmen Regional Research Center during 1987A/1988A are presented. The process of var. selection is carried out in 3 phases: F1C1, the 1st F1 clonal generation; preliminary yield trials; and yield trials. The selection criteria applied in each trial are detail...

Se presentan los resultados de investigacion realizada en el Centro Regional de Investigacion El Carmen durante 1987A-1988A. El proceso de seleccion var. se realiza en 3 fases consecutivas: F1C1 la primera generacion clonal de F1, ensayos preliminares de rendimiento y ensayos de rendimiento. Se d...

The most important quality factors are identified for each end use given to cassava (human consumption, animal consumption, starch production). Information available on the effects of harvest time, plant age, soil/climatic factors, and abiotic factors (pests and diseases) on cassava quality param...

Se identifican los factores de calidad mas importantes para cada uso de la yuca (consumo humano, consumo animal, produccion de almidon). Se resume la informacion existente sobre el efecto que la epoca de cosecha, la edad de la planta y los factores edaphoclimaticos y bioticos (plagas y enfermedad...

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 efficiency of different selection criteria (root wt., aerial part wt., total wt., no. of roots/plant, HI) applied to segregating populations of cassava crosses was assessed in expt. carried out at the Centro Nacional de Pesquisa de Mandioca e Fruticultura in Cruz das Almas (Bahia, Brazil). Sa...

Se evaluo la eficiencia de diferentes criterios de seleccion (peso de la raiz, peso de la parte aerea, peso total, no de raices/planta, IC) aplicados a poblaciones segregantes de cruzamientos de yuca en expt. realizados en el Centro Nacional de Pesquisa de Mandioca e Fruticultura en Cruz das Alma...

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...
