Breeding cassava relies on a phenotypic recurrent selection that takes advantage of the vegetative propagation of this crop. Successive stages of selection (single row trial- SRT; preliminary yield trial – PYT; advanced yield trial – AYT; and uniform yield trials UYT), gradually reduce the number...


Barandica, Orlando JoaquiLenis, Jorge I.Calle, FernandoMorante, NelsonPérez, Juan C.Hershey, Clair H.Ceballos, H.[Cassava breeding II: phenotypic correlations through the different stages of selection]Cassava breeding II: phenotypic correlations through the different stages of selection

La deficiencia de vitamina A es un problema de enormes consecuencias en la salud pública de muchos países en desarrollo. El perfeccionamiento y difusión de variedades con altos contenidos de carotenoides provitamina A es una estrategia para resolver este problema. La yuca es un cultivo relevante ...

Past research developed reliable equations to base selections for high β-carotene on near-infrared spectroscopy (NIR) predictions (100 genotypes d−1) rather than with high-performance liquid chromatography (HPLC) (<10 samples d−1). During recent harvest, CIAT made selections based on NIR predicti...

Cassava (Manihot esculenta, Crantz) is an important food security crop, but it is becoming an important raw material for different industrial applications. Cassava is the second most important source of starch worldwide. Novel starch properties are of interest to the starch industry, and one them...

Breeding cassava relies on several selection stages (single row trial-SRT; preliminary; advanced; and uniform yield trials—UYT). This study uses data from 14 years of evaluations. From more than 20,000 genotypes initially evaluated only 114 reached the last stage. The objective was to assess how ...

Resumen: La yuca ¨Waxy¨, variedad AM 206-5, libre de amilosa, fue reportada en 2006 en el proyecto de mejoramiento de yuca del CIAT, que busca desarrollar genotipos con características especiales en el almidón presente en sus raíces. Los almidones libre de amilosa tienen diferentes propiedades f...
