Solanum tuberosum subsp. andigenum 4x
PI 233996 at Genesys
An andigena type tetraploid collected in Bolivia before 1956. GRIN notes resistance to PVX.
TPS. Poor survival. Irregular yellows. Long and matted stolons. Appears to be mostly short day.
Initial seed increase 0.5g. Poor survival with this one, so it might be a good idea to try it again.
