Avances en desarrollo de variedades de yuca aptas para cosecha extendida en el Caribe Colombiano.

Cassava is a crop with high capacity to store starch, a characteristic used by industry as a starchy source. Seasonality in cassava root production is one of the main problems for industry and growers since commercial varieties significantly decrease in dry matter content when crop is extended. To identify a genotype with high and stable dry matter content adapted to the Caribbean region, six genotypes, and three commercial controls, were evaluated in three localities of the dry and humid Caribe. Evaluations were done at 10, 14 and 18 months after planting. Result allowed to outline genotype SM2828-28 since it showed yield average of 29, 38, and 33 ton ha-1 and dry matter content of 36, 36,4 ND 34,9 at 10, 14 and 18 months after planting, respectively. In dry matter content, the outlined genotype resulted in significantly higher values compared to commercial varieties, showing a high potential as a as a new extended crop variety.
