Subspecies boundaries of the wild potatoes Solanum bulbocastanum and S. cardiophyllum based on morphological and nuclear RFLP data
Morphological data and single- to low-copy nuclear DNA restriction enzyme site data were used to test subspecies circumscriptions of Solanum bulbocastanum and S. cardiophyllum. A prior chloroplast DNA analysis showed these species to be part of two main clades: 1. S. bulbocastanum subsp. bulbocastan...

| description | Morphological data and single- to low-copy nuclear DNA restriction enzyme site data were used to test subspecies circumscriptions of Solanum bulbocastanum and S. cardiophyllum. A prior chloroplast DNA analysis showed these species to be part of two main clades: 1. S. bulbocastanum subsp. bulbocastanum, S. bulbocastanum subsp. dolichophyllum, S. bulbocastanum subsp. partitum, S. cardiophyllum subsp. cardiophyllum and S. cardiophyllum subsp. lanceolatum, and 2. S. cardiophyllum subsp. ehrenbergii and other Mexican diploid species. The nuclear DNA and morphological data showed S. cardiophyllum subsp. ehrenbergii to be slightly distinguishable from the other subspecies of S. cardiophyllum, and do not support the distinction of subspecies within either species. These data add to a growing body of evidence that there are too many wild potato taxa recognized. |

Se analizan los límites intra-específicos de Solanum bulbocastanum y S. cardiophyllum utilizando caracteres morfológicos y sitios de restricción en ADN nuclear. Un estudio anterior, con base en sitios de restricción en ADN del cloroplasto, mostró a estas dos especies como parte de dos clados. El primero agrupó a S. bulbocastanum subsp. bulbocastanum, S. bulbocastanum subsp. dolichophyllum, S. bulbocastanum subsp. partitum, S. cardiophyllum subsp. cardiophyllum y S. cardiophyllum subsp. lanceolatum. El segundo incluyó a S. cardiophyllum subsp. ehrenbergii y otras especies diploides mexicanas. De acuerdo con los datos morfológicos y moleculares, S. cardiophyllum subsp. ehrenbergii es ligeramente diferente de las otras subespecies de S. cardiophyllum. Por otro lado, el análisis no apoya la distinción de subespecies. Por último, la información aquí presentada se suma a la evidencia publicada en otros artículos en el sentido del reconocimiento de un número demasiado alto de especies silvestres de papa.
