Based on the published descriptions of this species, it seems that I might have a mismatch here. I have gone back to the original genebank accessiona and confirmed that I get seedlings of the same type, so I’m not sure if this is an unusual accession of the species or a mistake by the genebank. As soon as I figure it out, I will make corrections.
Solanum huancabambense (huancabambense meaning from Huancabamba, Peru) is a species of small distribution in northern Peru. Plants reach a little more than a foot tall. Leaves are shiny and hairless (glabrous). White flowers. Overall this is a very attractive plant and it seems like it might have some ornamental potential.
This species resists the AVR2 effector of the late blight organism, one method of resistance to late blight (Aguilera-Galvez 2018). It most likely evolved this trait separately from North American species that have been more commonly used in late blight breeding, so it may be useful for broadening the genetic basis of that resistance. On the other hand, Garry (2001) found that late blight lesions were larger on S. huancabambense than on domesticated potato (possibly an indication of protective sensitivity to infection).
|Condition||Type||Level of Resistance||Source|
|Late Blight||Fungus||Somewhat resistant||Aguilera-Galvez 2018|
|Late Blight||Fungus||Not resistant||Gonzales 2002|
I have found this species difficult to germinate. It might require different conditions than the standard for S. tuberosum.
