Abstract

Solanum juzepczukii Buk. andSolanum curtilobum Juz. et Buk. are two important primitive cultivated species of potato which are planted in the highlands of Peru and Bolivia. Little natural variation exists within these species. Crosses were made to artificially recreate these species using tetraploid cultivated potatoes as female parents and triploids derived from acaule-diploid crosses as males. The new hybrids were tetraploid (2n = 48) with a high degree of heterosis and variability, and several potential cultivated clones possessing valuable characters such as yield, earliness, frost tolerance and good tuber type were selected.

Resumen

Solanum juzepczukii Buk. ySolanum curtilobum Juz. et Buk. son dos especies primitivas cultivadas que se siembran actualmente en las regiones altas de Perú y Bolivia. Existe poca variación natural dentro de estas especies por lo cual se hicieron intentos para obtener artificialmente numerosos clones, aumentar su variabilidad y dar la oportunidad de seleccionar nuevos fenotipos con mejores características. Los cruzamientos empleando papas cultivadas tetraploides como progenitores femeninos y triploides derivados de hibridos acaule-diploide como masculino dieron como resultado nuevos hibridos con 2n = 48 que tuvieron un alto grado de heterosis y variabilidad. Esto dió la oportunidad para seleccionar clones con caracteristicas valiosas tales como alta producción, precocidad, tolerancia a heladas y buen tipo de tubérculos.
