Yacon accessions with chromosome number determined

Yacon accessions with chromosome number determined

The chromosome number and ploidy level of 19 accessions from the Yacon (Smallanthus sonchifolius) collection of the CIP genbank were determined in meristematic cells of roots sprouted from stem cuttings using an optical microscope. A total of 18 accessions were octoploid (2n=6A+2B=58) and only one accession was dodecaploid (2n=9A+3B=87). It has been proposed that the Yacón has a hybrid origin in which two wild species would be involved, possibly S. riparius and S. macroscyphus. Based on this hypothesis, it can be said that 18 accessions were octoploid (2n=6A+2B=58) and only one accession was dodecaploid (2n=9A+3B=87).

Accesiones de Yacon con número de cromosomas determinado

El número de cromosomas y el nivel de ploidía de 19 accesiones de la colección de Yacon (Smallanthus sonchifolius) del banco de germoplasma del CIP fue determinado en células meristemáticas de raíces brotadas a partir de esquejes de tallo usando un microscopio óptico. Se ha propuesto que el Yacón tiene un origen híbrido en el que estarían involucradas dos especies silvestres, posiblemente S. riparius and S. macroscyphus. En base a esta hipótesis, se puede decir que 18 accesiones resultaron octoploides (2n=6A+2B=58) y unicamente una accesión resultó dodecaploide (2n=9A+3B=87).
