dc.description | The objective of this study was to evaluate the level of tolerance or susceptibility of different cultivars of tanier (Xanthosoma spp.) to root rot caused by Sclerotium roifsii, Rhizoctonia solani, Fusarium solani, Pythium sp., two pathogenic bacteria, and the combination of all the above mentioned pathogens associated with the disease. Under greenhouse conditions, we studied tanier cultivars with different levels of natural and induced polyploidy.The cultivars used were Palma, natural tetraploid (2n = 52); Venezolana, natural pentaploid (2n = 65); Amarilla del País, artificial tetraploid induced with coach (2n = 52); and Amarilla del País, natural diploid (2n = 26). The artificial tetraploid developed from Amarilla del Pais showed the highest percentage of root rot for all the pathogen treatments, higher than that of the natural diploid from which it was originated. The cultivars Palma and Venezolana showed a lower percentage of infection than cultivar Amarilla del País (tetraploid). | en-US |
dc.description | Se evaluó la susceptibilidad de diferentes cultivares de yautía (Xanthosoma spp.) a la pudrictón radicular mediante inoculación con Sclerotium rolfsii, Rhizoctonia solani, Fusarium solani, Pythium sp., dos bacterias patogénicas, y la combinación de todos los organismos descritos. Se utilizaron cultivares de yautía con diferentes niveles de ploidía. Estos fueron Palma, tetraploide natural (2n = 52); Venezolana, pentaploide natural (2n = 65); Amarilla del País, tetraploide artificial inducido con colchicina (2n = 52); y Amarilla del País, diploide natural (2n = 26). El tetraploide artificial desarrollado del cultivar Amarilla del País mostró el porcentaje más alto de raíces podridas con todos los patógenos evaluados, por encima del obtenido por el diploide natural del cual se originó. Los cultivares Palma y Venezolana desarrollaron un porcentaje menor de raíces podridas que el cultivar Amarilla del País (tetraploide). | es-ES |
