Flowering in cassava is related to branching. Erect plant architecture is usually preferred by farmers but results in late and scarce flowering, which slows down breeding and genetic studies. The objective of this study was to induce earlier and more abundant flowering, which have become key rese...

This 14-minute video describes the protocol used for the collection of female flowers at different ages after anthesis and the development of a protocol of early embryo rescue. The production of doubled haploids through different gynogenesis approaches usually require an early rescue of embryos w...

Cassava biofortification programs have made significant progress in improving pro-vitamin A carotenoid (pVAC) content; however, the nutritional impact of traditional and industrial food processing has not been fully assessed. The effects of fermentation and thermal processing on the stability and...

Identifying crop research priorities based on potential economic and poverty reduction impacts: The case of cassava in Africa, Asia, and Latin America
Ten and thirty cassava genotypes producing wildtype and amylose‐free (waxy) starch respectively, are grown at low (LA) and intermediate (IA) altitudes (<213 and >900 m above sea level (m.a.s.l.) respectively). The functional properties of the starch from these materials are analyzed. The relative...

Cassava is an important energy source in the diets of millions of people in tropical and subtropical regions of the world. It is a key subsistence crop, and its industrial uses are steadily growing. In spite of its economic and social relevance, relatively little investment has been made for rese...
