Ploidy and morphological characteristics of Solanum tuberosum × Solanum phureja hybrids

Pflügers Archiv - European Journal of Physiology, 2000
In attempt to induce doubled haploids in potato we studied interspecific hybrids between tetraploid Solanum tuberosum cultivars Igor, Jana, Vesna, Romano, Arinda, Fianna, Donald and Vital and Solanum phureja (clone IVP 48). Four out of eight cultivars produced 21 berries in total and 149 seedlings were obtained.

Resistance to bacterial wilt in somatic hybrids between Solanum tuberosum and Solanum phureja

Plant Science, 2000
Somatic hybrid plants were produced after protoplast electrofusion between a dihaploid potato, cv. BF15, and a wild tuber-bearing relative, Solanum phureja, with a view to transferring bacterial wilt resistance into potato lines. A total of ten putative hybrids were selected.

Genetic analysis of protoplast culturability in Solanum phureja

Plant Science, 1991
Abstract Protoplast culturability, defined as the ability of a genotype to develop calli from cultured protoplasts, was studied in the diploid potato species, Solanum phureja Juz. and Buk. A protoplast non-culturable, androgenetically derived homozygous line, AM3-8, was crossed with a protoplast culturable selection, NBP2.

Breeding behavior for tuber protein in Solanum tuberosum and Tuberosum-phureja hybrids

Euphytica, 1981
True protein content among tubers within a plant of Solanum tuberosum cv. Oneida was found to be negatively correlated with tuber size. A similar study of S. phureja genotype 148-17 revealed no correlation. Tuber protein was determined for 250 genotypes in each of four hybrid potato populations in a factorial mating design with four potato cultivars as

Elimination of Solanum phureja nucleolar chromosomes in S. tuberosum + S. phureja somatic hybrids

Theoretical and Applied Genetics, 1987
The 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 ...

Comparison of carotenoid and anthocyanin profiles of raw and boiled Solanum tuberosum and Solanum phureja tubers

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.

Cytological and molecular observations on Solanum phureja-induced dihaploid potatoes

Theoretical and Applied Genetics, 1991
Seventeen 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

Solanum phureja genes are expressed in the leaves and tubers of aneusomatic potato dihaploids

Euphytica, 1993
The expression of leaf isozymes and tuber patatin in dihaploids derived from the Solanum tuberosum cv. Pentland Crown was investigated. Seven of the dihaploids were aneusomatic containing additional chromosomes from the S. phureja dihaploid inducer. Of these, four genotypes expressed leaf isozymes characteristic of the S. phureja dihaploid inducer, and

Variation for 2n pollen production in clones of Solanum phureja Juz. and Buk.

Theoretical and Applied Genetics, 1981
Frequency of unreduced pollen grains was estimated for five genotypes of Solanum phureja (2n=24) growing in three environments; (E1) cool (7.2-13.3°C) and (E2) warm (12.2-17.2°C) growth chambers and (E3) field conditions. Highly variable frequencies were found, with genotype, environment, and genotype x environment interaction as significant components
