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.

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.
