Solanum tuberosum subsp. andigenum 2x
A stenotomum type diploid collected in Bolivia before 1956. GRIN notes resistance to Fusarium, PVM, ringrot, PSTVd. S type cytoplasm (Hosaka 1988).
TPS. Tubers elongate. Whites, reds, yellows, and a few blues. Mostly white to light yellow flesh. Shallow to medium eyes. Mostly short day. Majority sprouting at harvest. Low to moderate flowering and berrying. Very low seed counts per berry.
As near as I can tell, “thanta guagua” translates in Aymara to “bread baby.”
