El cultivo de la yuca en Panama
In Panama most of the cassava is produced by small farmers on marginal, infertile soils with a low level of technology. One of the main cassava producing areas is Ocu, where Ultisols prevail. The most commonly grown var. is Brasilena, with av. yields of 10-12 t/ha. Production constraints include pri...

| description | In Panama most of the cassava is produced by small farmers on marginal, infertile soils with a low level of technology. One of the main cassava producing areas is Ocu, where Ultisols prevail. The most commonly grown var. is Brasilena, with av. yields of 10-12 t/ha. Production constraints include price fluctuation, quick saturation of traditional markets for fresh roots, and the resulting production surpluses. Research on the crop is carried out by the Instituto de Investigacion Agropecuaria de Panama; objectives of plant breeding are to (1) increase the available genetic variability, (2) select high yielding, stable germplasm adapted to the Panamanian ecosystem, and (3) select genotypes adapted to highly acid soils and prolonged droughts in addition to other genotypes apt for agroindustrial purposes. More than 40 genotypes have been introduced in vitro and over 600 F1 lines in the form of botanical seed. Among the introductions, Dayana performed well with yields of 32 t/ha in observation and preliminary yield trials. Other promising genotypes are Brasilena, Chiru, Gigante, and China Amarilla. The infrastructure necessary for international germplasm exchange exists. Mechanisms to effectively multiply and distribute new var. to farmers should be promoted and developed. (CIAT) |

(CIAT) En Panama la mayor parte de la yuca es producida por pequenos agricultores en suelos marginales e infertiles y con un nivel tecnologico bajo. Una de las areas de mayor produccion es Ocu, con suelos Ultisoles en su mayoria. La var. Brasilena es la mas cultivada a nivel nacional con un rendimiento prom. de 10-12 t/ha. Entre los factores que afectan la produccion del cultivo estan la fluctuacion en los precios, la rapida saturacion de los mercados tradicionales de consumo fresco y los consecuentes excedentes de produccion. La investigacion en yuca la realiza el Instituto de Investigacion Agropecuaria de Panama; en cuanto a mejoramiento genetico, se intenta aumentar la variabilidad genetica disponible, seleccionar germoplasma con adaptacion al ecosistema panameno y con altos y estables rendimientos y seleccionar genotipos con adaptacion a suelos con alta acidez y sequias prolongadas ademas de otros aptos para la agroindustrializacion. Se ha introducido mas de 40 genotipos in vitro y mas de 600 lineas F1 por medio de semillas botanicas. Entre las introducciones se ha destacado Dayana con rendimientos de 32 t/ha en ensayos de observacion y ensayos preliminares de rendimiento. Otros genotipos promisorios son Brasilena, Chiru, Gigante y China Amarilla. Se cuenta con las instalaciones necesarias para el intercambio internacional de germoplasma. Es necesario promover y desarrollar mecanismos de multiplicacion y distribucion efectiva de las nuevas var. para que sean adoptadas por los agricultores.
