In: Tropical Root and Tuber Crops BulletinSummary: Ensayos realizados con cruzamientos interespecificos de 5 var. de yuca con las especies relacionadas Manihot epruinosa y M. glaziovii indicaron que los niveles de ploidia (2x, 3x, 4x) se pueden manipular tanto sexual como asexualmente. La poliploidizacion se asocia con la formacion de gametos 2n. Los triploides generalmente presentan un mejor desempeno y mejor arquitectura de la planta que los tetraploides. Por tanto, los triploides son mas promisorios que los tetraploides, se han producido y se estan sometiendo a evaluaciones posteriores. (CIAT)Summary: Trials carried out with interspecific crosses of 5 cassava var. with related species Manihot epruinosa and M. glaziovii indicated that ploidy levels (2x, 3x, 4x) can be manipulated sexually and asexually. Sexual polyploidization is associated with 2n gamete formation. Triploids generally perform better and have better plant architecture than tetraploids. Therefore, triploids are more promising than tetraploids, have been produced, and are being subject to further evaluation. (CIAT)
