Elimination of Solanum phureja nucleolar chromosomes in S. tuberosum + S. phureja somatic hybrids
Theoretical and Applied Genetics, 1987The karyotype of the dihaploid SVP1 line of S. tuberosum (2n=2x=24) showed two nucleolar chromosomes with differently sized satellites. The diploid SVP5 line (2n=2x=24) and tetraploid regenerants of S. phureja had larger but similar satellites. Somatic hybrids between the diploid lines of these potato species with genome combinations 4 tub + 2 ph ...

Cytological and molecular observations on Solanum phureja-induced dihaploid potatoes
Theoretical and Applied Genetics, 1991Seventeen potato dihaploids, produced by pollinating the tetraploid (2n = 48) cv 'Pentland Crown' with pollen from Solanum phureja (2n = 24) dihaploid inducer clones, were studied. Since dihaploids are thought to develop parthenogenetically from unfertilized ovules they were expected to be euploid (2n = 24), but somatic chromosome counts showed that 15

Somatic Hybridization Between Solanum tuberosum L. (Potato) and Solanum phureja
2001Solanum tuberosum is the fourth most important food crop in the world, after rice, maize and wheat. The common potato is of ancient origin, originally domesticated as a range of diploid types in South America. Spontaneous tetraploid lines arose in the Lake Titicaca area and these were brought to Europe during the latter part of the 16th century The ...

Effect of Light Exposure on the Glycoalkaloid Content of Solanum phureja Tubers
Journal of Agricultural and Food Chemistry, 2001The individual glycoalkaloid contents of tubers from eleven Solanum phureja genotypes have been determined prior to and following exposure to light. In all genotypes, light exposure resulted in a statistically significant increase in total glycoalkaloid content. In nine of the genotypes studied, this was not only due to an increase in the levels of the

Photo-induced synthesis of tomatidenol-based glycoalkaloids in Solanum phureja tubers
Phytochemistry, 2000The effect of light exposure on the steroidal glycoalkaloid content of Solanum phureja tubers has been investigated and compared with that in domesticated potato (Solanum tuberosum) tubers. The results indicated that the increase in the concentration of solanidine-based glycoalkaloids, alpha-solanine and alpha-chaconine was broadly similar in both ...

Journal of Food Composition and Analysis, 2011
Abstract Tubers of the closely related species Solanum tuberosum (potatoes) and Solanum phureja belong to the staff of life for humans. The coloration of the often very colorful tubers is caused by carotenoids (especially xanthophylls) and anthocyanins. The new S. phureja cultivars Mayan Gold and Mayan Twilight, the new S.

AFLP markers were used to build a core subset in 144 accessions of the United States Potato Genebank (USPG) ex situ collection of the species formerly known as Solanum phureja (now reclassified as Solanum tuberosum L. subsp. andigenum). A core subset aims to sample the minimum number possible of non-redundant germplasm units capturing the maximum ...

Phenotypic variation and correlations between monoploids and doubled monoploids of Solanum phureja
Euphytica, 1991Ten anther-derived monoploids, twelve doubled monoploids and the heterozygous anther donor clone of Solanum phureja were compared for six vegetative, eight reproductive and three yield characters in the greenhouse. Significant high correlations were observed between the monoploids and their doubled monoploids for 14 of 17 characters. Therefore, doubled

Self -Compatibility in a Diploid Hybrid Population of Solanum phureja – S. stenotomum
American Journal of Potato Research, 2018Recently proposals have been made in both Europe and North America to try to radically change potato breeding strategy from a tetraploid, heterozygous crop to a diploid inbred crop. As part of that effort, clones from the long-day adapted, late blight resistant diploid hybrid Solanum phureja – S.
