High temperatures affect potato production in the tropics, putting tuber yield and quality at risk and leading to increased glycoalkaloid concentration the cause of the bitter taste in potatoes and a cause for concern for human health. The International Potato Center (CIP), has developed new heat...


Gastelo, M.Díaz, L.Burgos, G.Felde, T. zumBonierbale, Merideth W.[Heritability for yield and glycoalkaloid content in potato breeding under warm environments.]Heritability for yield and glycoalkaloid content in potato breeding under warm environments.

Breeding efforts to develop high iron and zinc potatoes require a fast and inexpensive technique to evaluate mineral concentrations in large numbers of samples. In this study, we evaluated the feasibility of applying X-ray fluorescence spectrometry to estimate iron and zinc in freeze-dried and mi...

The major subsistence food systems of the world that feed resource?poor populations are identified and their capacity to supply essential nutrients in reasonable balance to the people dependent on them has been considered for some of these with a view to overcoming their nutrient limitations in s...

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”.

The determination of iron (Fe) and zinc (Zn) concentrations in 49 native Andean potato varieties revealed significant genotypic variation. Comparison of mineral concentrations of 37 of these germplasm accessions grown in two highland locations further revealed significant variation due to environ...
