Abstract

The leaf phenolics of the potato speciesS. × ajanhuiri, S. stenotomum, S. megistacrolobum and the artificial F1 S. stenotomum × S. megistacrolobum hybrids have been compared using thin layer chromatography

The wild potatoS. megistacrolobum produced unidentified phenolic compounds which were present in the artificialS. stenotomum × S. megistacrolobum hybrids and the YARI group ofS. × ajanhuiri, but which were absent inS. stenotomum. This further supports the hypothesis thatS. X ajanhuiri is of hybridogenic origin and was derived from natural crosses between the cultivatedS. stenotomum and the wildS. megistacrolobum.

Resumen

Los compuestos fenólicos de las hojas de las especies de papaS. × ajanhuiri, S. stenotomum, S. megistacrolobum y los híbridos artificiales F1 S. stenotomum × S. megistacrolobum fueron comparados usando cromatografía en capa fina

La especie silvestreS. megistacrolobum produjo compuestos fenólicos no identificados que se encontraron presentes en los híbridos artificialesS. stenotomum × S. megistacrolobum y en el grupoYARI deS. × ajanhuiri, pero que estaban ausentes enS. stenotomum. Esto añade mayor soporte a la hipótesis de queS. × ajanhuiri es de origen hibridógeno y que fue derivado de cruces naturales entre la especie cultivadaS. stenotomum y la especie silvestreS. megistacrolobum.
