Little is known about the inheritance of agronomic traits in cassava, or on the relative importance of epistasis for most crops. A group of 10 clones, adapted to the acid-soils environment was used as parents in a diallel study. Thirty genotypes were obtained from each F1 cross and cloned. Each c...

El almidón de yuca presenta escasa variación en su calidad. Las mutaciones inducidas son una fuente de variación heredable para características deseables. Estas mutaciones, aunque se presentaran genéticamente, serian difíciles de detectar fenotípicamente debido a su alta heterocigosidad. El objet...

One of the objectives of the cassava-breeding project at CIAT is the identification of clones with special root quality characteristics. A large number of self-pollinations have been made in search of useful recessive traits. During 2006 harvests an S1 plant produced roots that stained brownish-r...
