Rapid-cycling recurrent selection has been implemented to produce cassava varieties that deliver provitamin A carotenoids to human populations that are affected by vitamin A deficiency. Rapid-cycling
selection relies on quantification in just one plant per genotype. This study was conducted to a...

Sampling strategies for proper quantification of carotenoid content in cassava breeding
Post-harvest physiological deterioration (PPD) is one of the most important constraints in cassava production and commercialization. It has been hypothesized that the antioxidant properties of carotenoids in yellow cassava roots may help reduce or delay PPD. The industrial sector prefers cassava ...

Cassava (Manihot esculenta Crantz) is one of the most important sources of starch in the tropics. There is limited and contradictory information regarding cassava starch characteristics. The International Center for Tropical Agriculture (CIAT) holds in trust FAO's cassava germplasm collection. St...

About 70 million people obtain more than 500 cal per day from cassava roots. The crop is fundamental as food security of poor rural communities, but little is known about variability of root nutritional and quality traits. Roots from 2457 genotypes comprising landraces and improved clones, were s...

Los extractos foliares (EF) son utilizados como complemento nutricional en países como Nicaragua y Tanzania. Se evaluaron hojas y EF de yuca, fríjol, batata y alfalfa, y se cuantificó los componentes nutricionales, antinutricionales y biodisponibilidad por métodos in vitro. En promedio (DE), el E...

Few natural waxy starches are offered to the industry demand. Therefore, the morphological, physical, and chemical characteristics of “Mapuey” waxy starch were assessed. Amylose contents of starches isolated from Dioscorea trifida L. (“Mapuey”) landraces cultivated in the Amazons of Venezuela wer...

For mutants of starch and other desirable traits of interest in cassava, we evaluated the physical-chemical morphology of the root and paste in inbred populations of six M2 families, derived from irradiated seeds. 1,097 plants were established, 829 of Gamma treatment and 268 of neutrons. In the m...
