“…The rankings of the cultivars according to the tuber concentrations of the two minerals were identical indicating a positive correlation between the genotypic concentrations of the two minerals, which was also found in previous work with native Andean potatoes in Peru (Burgos et al 2007) and in other studies with potato (Carli and Khalikov 2008;Brown et al 2010;Lefèvre et al 2012). The ranking of the cultivars was maintained at all sites and following Fe and Zn fertilizer applications (Table 6).…”

“…Previous studies have shown similar strong site effects on tuber mineral concentrations (Burgos et al 2007;Brown et al 2010;Haynes et al 2012;Nassar et al 2012). Burgos et al (2007) reported a variation in tuber Fe concentration in the 3-fold range among sites in Peru, whereas Brown et al (2010) reported a 4-fold difference in Fe tuber concentrations among sites in the United States.…”

It is noteworthy that the sites in our trials resulting in the lowest tuber Zn concentrations, Tunshi and Cortijo Bajo, were sites with high soil calcium concentrations and relatively high pH.…”

Aims The aim of this study was to investigate the proofof-concept that Andean potato (Solanum tuberosum L., Andigenum Group) can be agronomically biofortified with iron (Fe) and zinc (Zn) fertilizers. Methods Greenhouse and field experiments were conducted in the Ecuadorian Andes with varying rates of foliar and soil applied Fe and Zn fertilizers to investigate the potential resulting increase in tuber Fe and tuber Zn concentrations.Results The study showed that simple fertilizer practices enhancing Zn supply to potato plants can increase tuber Zn concentrations. The rate of increase of tuber Zn following Zn fertilization was similar across cultivars. A concomitant negative effect of high rates of Zn applications on yield was not seen, and a maximum Zn application level for increasing tuber Zn concentration was not identified. A positive tuber yield effect was seen at one field site. High rates of foliar Zn application reached a 2.51-fold tuber Zn increase, and high rates of soil Zn application a 1.91-fold tuber Zn increase. The experiments showed no positive correlation between Fe fertilization and Fe concentration in tubers. Moreover, the study showed a strong effect of site on the concentration of Fe and Zn in tubers, and the tuber mineral concentrations across sites and treatments were negatively correlated with tuber yield. Conclusions The results confirmed the proof of concept that Andean potato cultivars can be agronomically Znbiofortified with foliar and soil applied Zn fertilizers. Tuber Fe concentrations of Andean potatoes were not increased with Fe fertilization.

“…In a previous publication (Brown et al 2010) the iron content of the genotypes in these trials was reported. The correlation of iron and zinc was positive and highly significant in the Regional Red/Specialty Trial (r=0.84, P<0.01), not significant in the Regional Russet Trial and highly significantly negatively correlated in the Tri-State Trial (r=−0.70, P<0.01).…”

The mineral content of potato is an important consideration in the evaluation of its role in the human diet. Zinc content is vital due to its crucial role as a micronutrient. Zinc deficiency occurs among the poorest of the world's populations. In this study, 36 breeding lines and varieties (genotypes) were divided among three trials (Tri-State, Western Regional Russet and Western Specialty/Red) which were grown in 11 locations. Zinc content was measured in harvested tubers by wet ashing and passage through an Inductively Coupled Argon Plasma Emission Spectrophotometer Genotype mean zinc content ranged from 12 to 18 μg g −1 dry weight over all trials. In two of the three trials there were no significant differences among genotypes for zinc. Broad sense heritabilities for zinc content were small in these two trials. In the Western Regional Russet Trial there were significant differences among genotypes and the heritability was 0.61, suggesting that genotypes with higher zinc content could be selected. However, the largest zinc value was only 50% above the lowest value. Furthermore, a 100 g serving of the highest zinc genotype would only provide 4% of the adult Estimated Average Requirement From these results, potato from this breeding pool would not appear to be a good candidate for biofortification of zinc through traditional breeding. Higher values from other studies suggest that zinc biofortification through breeding may be warranted in potato for populations with high potato consumption and high risk for zinc deficiency in the Andes of South America.Resumen El contenido mineral de la papa es de consideración importante en la evaluación de su papel en la dieta humana.

En este estudio, se dividieron 36 líneas de mejoramiento y variedades (genotipos) en tres ensayos (Tres-Estados, Russet Regional del Oeste y especialidad roja del oeste) establecidos en 11 localidades.

“…This suggests that breeding for high tuber Ca, Fe and Zn concentrations might have potential. Furthermore, the heritability of tuber mineral concentrations in potato were found to be moderately high (Brown et al 2010(Brown et al , 2011(Brown et al , 2012(Brown et al , 2013(Brown et al and 2014Haynes et al 2012;Paget et al 2014;Zorrilla et al 2014), indicating the possibility of mineral biofortification by plant breeding.…”

Abstract:The variation in tuber mineral concentrations amongst accessions of wild tuber-bearing Solanum species in the Commonwealth Potato Collection (CPC) was evaluated under greenhouse conditions. Selected CPC accessions, representing the eco-geographical distribution of wild potatoes, were grown to maturity in peat-based compost under controlled conditions. Tubers from five plants of each accession were harvested, bulked and their mineral composition analysed. Among the germplasm investigated, there was a greater range in tuber concentrations of some elements of nutritional significance to both plants and animals, such as (Ca, Fe and Zn; 6.7, 3.6, and 4.5-fold respectively) than others, such as (K, P and S; all <3-fold). Significant positive correlations were found between mean altitude of the species' range and tuber P, K, Cu and Mg concentrations. The amount of diversity observed in the CPC collection indicates the existence of wide differences in tuber mineral accumulation among different potato accessions. This might be useful in breeding for nutritional improvement of potato tubers.
