Somatic Hybridization Between Solanum tuberosum L. (Potato) and Solanum phureja

2001
Solanum 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, 2001
The 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, 2000
The 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 ...

Age- and Organ-Specific Differences of Potato (Solanum phureja) Plants Metabolome

Russian Journal of Plant Physiology, 2018
Potato Solanum phureja Juz. & Bukasov crop species' metobolome at the flowering stage includes 234 compounds, 117 of which were identified. The most represented group among them contains sugars and their derivatives that are in accordance with intensive carbohydrate exchange of potato tissues and organs.

Characterisation of resistance to potato leafroll virus accumulation in Solanum phureja

Euphytica, 1999
Strong resistance to accumulation of potato leafroll virus (PLRV) was identified in a clone of the diploid potato species Solanum phureja (cv. ‘Egg Yolk’, clone 5010) using a quantitative enzyme-linked immunosorbent assay (ELISA). The resistance is expressed very strongly in leaf tissue (virus could not be detected in leaves of some plants although ...

An AFLP Marker Core Subset for the Cultivated Potato Species Solanum phureja ( Solanum tuberosum L. subsp. andigenum)

American Journal of Potato Research, 2021
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 ...

Self -Compatibility in a Diploid Hybrid Population of Solanum phureja – S. stenotomum

American Journal of Potato Research, 2018
Recently 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.

Macronutrient contents of potato genotype collections in the Solanum tuberosum Group Phureja

Journal of Food Composition and Analysis, 2018
Abstract Macronutrient contents of 94 genotypes from the Colombian Central Collection (CCC) and 13 genotypes from the Native Collection (NC) of diploid potatoes (Solanum tuberosum Group Phureja) were evaluated, considering six genotypes, four diploid and two tetraploid potato commercial cultivars, as control.

Phenotypic variation and correlations between monoploids and doubled monoploids of Solanum phureja

Euphytica, 1991
Ten 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

A two-loci system of gametophytic incompatibility in Solanum phureja and S. stenotomum

Euphytica, 1971
A two-loci gametophytic incompatibility system is indicated in our experiments involving hybrids between S. phureja accessions and between S. stenotomum and S. phureja. The S locus is epistatic to the R locus. An allele Rfi at the latter locus when present in homozygous condition, leads to female incompatibility, independent of the genotype of the ...
