Partial resistance to late blight (Phytophthora infestans) in hybrid progenies of four South American Solanum species crossed with diploid S. tuberosum [PDF]

Theoretical and Applied Genetics, 1995
Resistant genotypes of the diploid tuber-bearing South American species Solanum arnezii × hondelmannii, S. berthaultii, S. leptophyes and S. microdontum were crossed with three diploid genotypes of S. tuberosum that varied in resistance and maturity type.

Two related genotypes of Solanum microdontum carry different segregating alleles for field resistance to Phytophthora infestans

Molecular Breeding, 2000
Six F1 populations produced from crosses between two Solanum microdontum genotypes and three S. tuberosum genotypes have been assessed for resistance to Phytophthora infestans (late blight; LB) in the field and proved to segregate for P. infestans resistance. The six populations were subjected to genetic mapping using AFLP markers in combination with a

Epigenetic consequences of interploidal hybridisation in synthetic and natural interspecific potato hybrids [PDF]

New Phytologist, 2019
Interploidal hybridisation can generate changes in plant chromosome numbers, which might exert effects additional to the expected due to genome merger per se (i.e., genetic, epigenetic and phenotypic novelties).Wild potatoes are suitable to address this ...

An Improved Method Involving Hydroponic Culture for the Production of Sexual Hybrids between DihaploidSolanum tuberosumand Diploid S.microdontum

Journal of Experimental Botany, 1992
Dihaploid Solanum tuberosum and diploid S. microdontum plants were grown in soil and hydroponics under glasshouse and growth room conditions. A high light intensity was necessary for flower induction in both species and the dihaploid flowered only when grown in hydroponics.

Reproducible Quantitative Trait Loci for Resistance to Soft Rot Caused by Dickeya dianthicola Derived from the Wild Potato Solanum microdontum (PI 458355) Are Located on Chromosomes 1, 3, and 5

Phytopathology®
The potato wild relative Solanum microdontum is a breeder-friendly source of genetic resistance to soft rot. Our objectives were to (i) identify loci associated with soft rot resistance in S. microdontum germplasm and (ii) develop bi-parental populations in a self-compatible S.
