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...
