Genetic Resources (Including Wild and Cultivated Solanum Species) and Progress in their Utilisation in Potato Breeding (2006, background): “phureja, thus allowing breeding at the diploid level before returning to the tetraploid level for cultivar production (Jansky et al., 1990; Carputo and Barone, 2005).”
Utilisation of the Commonwealth Potato Collection in potato breeding (2005, background): “The schemes used for ploidy level manipulations exploit the facts that unreduced 2n gametes are common in Solanum species and maternal haploids (dihaploids) of tetraploid S. tuberosum can be extracted following crosses with pollinator clones of S. phureja, thus allowing breeding at the diploid level”
Towards F1 Hybrid Seed Potato Breeding (2011, unknown): “As long as the underlying mechanisms of the phenotype changes in polyploid crops are unknown, plant performance at various ploidy levels should be empirically tested and the results applied in practice (Carputo and Barone 2005).”
Reinventing potato as a diploid inbred line-based crop (2016, background): “The number of these lines is small, however, and they have been developed with the intention of introgressing those traits into tetraploid potato via 2n gametes (Carputo and Barone, 2005; Ortiz et al., 2009).”
