Natural hybridization between Solanum acaule Bitt. and S. megistacrolobum Bitt. in the province of Jujuy, Argentina


, : Natural hybridization between Solanum acaule Bitt. and S. megistacrolobum Bitt. in the province of Jujuy, Argentina. Euphytica 31(3): 817-835

Evidence is provided that hybridization of the tetraploid (2n = 4x = 48), self-fertile, tuber-bearing species S. acaule with the diploid (2n = 2x = 24), self-incompatible, tuber-bearing S. megistacrolobum takes place in several localities of Jujuy in the high, cold plateaux of the Argentine Puna.
