Lindqvist-Kreuze, HaneleKhan, A.Salas, E.Meiyalaghan, S.Thomson, S.Gómez, R.Bonierbale, Merideth W.[Tuber shape and eye depth variation in a diploid family of Andean potatoes.]Tuber shape and eye depth variation in a diploid family of Andean potatoes.

One of the future challenges to produce food in a Mars environment will be the optimization of resources through the potential use of the Martian substratum for growing crops as a part of bioregenerative food systems. In vitro plantlets from 65 potato genotypes were rooted in peat-pellets substra...


Ramírez, D.Kreuze, J.F.Amoros, W.Valdivia Silva, J.E.Ranck, J.García, S.Salas, E.Yactayo, W.[Extreme salinity as a challenge to grow potatoes under Mars-like soil conditions: targeting promising genotypes.]Extreme salinity as a challenge to grow potatoes under Mars-like soil conditions: targeting promising genotypes.

The ascorbic acid (AA) concentration of tubers was determined in 25 Andean potato varieties (Solanum tuberosum L.) grown in three environments, and the effect of cooking and storage time in subsets of samples was evaluated. Significant variation due to genotype, environment and genotype × environ...


Burgos, G.Auqui, S.Amoros, W.Salas, E.Bonierbale, Merideth W.[Ascorbic acid concentration of native Andean potato varieties as affected by environment, cooking and storage.]Ascorbic acid concentration of native Andean potato varieties as affected by environment, cooking and storage.

Samples from unprocessed and processed cooked tubers of the nine most abundant potato cultivars used to prepare the traditional freeze-dried food product, “chuño” in the central highlands of Peru were prepared and analyzed for their protein and mineral concentrations. The protein, iron, zinc and ...


Burgos, G.Haan, Stef deSalas, E.Bonierbale, Merideth W.[Protein, iron, zinc and calcium concentrations of potatoes following traditional processing as “chuño”.]Protein, iron, zinc and calcium concentrations of potatoes following traditional processing as “chuño”.
Haan, Stef deBurgos, G.Ccanto, Raul I.Arcos, J.Scurrah, M.Salas, E.Bonierbale, Merideth W.[Effect of production environment, genotype and process on the mineral content of native bitter potato cultivars converted into white chuño.]Effect of production environment, genotype and process on the mineral content of native bitter potato cultivars converted into white chuño.
Paget, M.Amoros, W.Salas, E.Eyzaguirre, R.Alspach, P.Apiolaza, L.Noble, A.D.Bonierbale, Merideth W.[Genetic evaluation of micronutrient traits in diploid potato from a base population of Andean Landrace Cultivars.]Genetic evaluation of micronutrient traits in diploid potato from a base population of Andean Landrace Cultivars.
Bonierbale, Merideth W.Gruneberg, W.J.Amoros, W.Burgos, G.Salas, E.Porras, E.Felde, T. zum[Total and individual carotenoid profiles in Solanum phureja cultivated potatoes. 2: Development and application of near-infrared reflectance spectroscopy (NIRS) calibrations for germplasm characterization.]Total and individual carotenoid profiles in Solanum phureja cultivated potatoes. 2: Development and application of near-infrared reflectance spectroscopy (NIRS) calibrations for germplasm characterization.

Starch was extracted from twenty-four accessions of Group Phureja cultivated diploid potatoes, and from two commercial potato (Solanum tuberosum) varieties. Extracted starch samples were characterized and compared to industrial potato starch. Starch from Phureja generally exhibited smaller granul...


Caceres, MMestres, CPons, BGilbert, O.Amoros, W.Salas, E.Dufour, DominiqueBonierbale, Merideth W.Pallet, D[Physico-chemical characterization of starches extracted from potatoes of the group Phureja]Physico-chemical characterization of starches extracted from potatoes of the group Phureja

Total and individual carotenoid concentrations were determined by spectrophotometry and HPLC, in raw tubers of a sample of 23 accessions of Solanum phureja potatoes taken at random from the world germplasm collection following its stratification on tuber flesh color. Lutein, zeaxanthin, violaxant...
