Inheritance of freezing resistance in tuber-bearing Solanum species: evidence for independent genetic control of nonacclimated freezing tolerance and cold acclimation capacity.
The results show that it should be possible to incorporate the two main traits associated with frost or winter survival from wild germ plasm into cultivated crop plants by independent selection, and demonstrates relative simplicity of the inheritance of cold acclimation. Expand
The R1 resistance gene cluster contains three groups of independently evolving, type I R1 homologues and shows substantial structural variation among haplotypes of Solanum demissum.

The results suggest that the R1 homologues represent three independent groups of fast-evolving type I resistance genes, characterized by chimeric structures resulting from frequent sequence exchanges among group members. Expand
Wild potatoes (Solanum section Petota; Solanaceae) of North and Central America
Solanum section Petota, the potato and its wild relatives, contains about 200 wild species distributed from the southwestern United States, to central Argentina and adjacent Chile. Although mostExpand
Screening of exotic potato germplasm for nitrogen uptake and biomass production
A “mini” core collection of wild germplasm for biomass production, N uptake, and N use efficiency was evaluated during the 1993 growing season at Becker, Minnesota, with significant effects on total dry weight, N content, and tissue N concentration. Expand
Evaluation of tuber-bearingSolanum species for nitrogen use efficiency and biomass partitioning
Of the wild species tested, S. chacoense accessions had the highest biomass accumulation and N uptake efficiencies and may be the best source of germplasm for improving NUE in a potato breeding program. Expand
Reinventing potato as a diploid inbred line-based crop
This paper proposes to convert potato into a diploid inbred line–based crop propagated by true seed and calls on leaders of public and private organizations to explore the feasibility of this radical and exciting new strategy in potato breeding. Expand
Geographical and environmental range expansion through polyploidy in wild potatoes (Solanum section Petota)
It is suggested that polyploidy played an important role in this group of wild potatoes’ environmental differentiation and range expansion. Expand
Potato genetic resources: Sources of resistance and systematics
Examples of the proven and potential utility of wild and cultivated landrace members of sect.Petota for reducing the authors' reliance on chemical controls for many pests and diseases that affect commercial cultivars are provided and an overview of the status of germplasm availability and taxonomy of these species is provided.

This extreme 8 year tuber dormancy in S. jamesii should be a valuable research tool for study of dormancy physiology in potato. Expand
Rapid ploidy screening of tuber-bearingSolanum (potato) species through pollen diameter measurement
Although it is not effective in distinguishing 4x and 6x sporophytes, microscopic pollen diameter measurement is a very rapid and reliable method by which to distinguish 2x from 4x or 6xporophytes. Expand
