“…In general, the contents of N, P, K, S, Ca and Mg are similar to those, reported by other authors working on potatoes (Rivero et al, 2003;Tekaling and Hammes, 2005;Andre et al, 2007;DiGiacamo et al, 2007). The present study also showed that the N, P, K and S content of accession AC 10062, AC10069 and AC10110 were higher than the Bangladeshi variety Diamant and Cardinal, which are also high yielding (Kabir 2014).The levels of Cu, Mn, and Zn in this study are alike with those reported by Haynes et al (2012). They observed average Mn, Cu, and Zn contents were 10.2, 9.9, and 20.0 mg kg −1 of FW, respectively and concluded that genetic variation had significant influence on micronutrient contents of potato.…”

Twenty two potato accessions from USA were evaluated for nutrient contents. Two Bangladeshi varieties were also included for comparison. Nutritional analyses were performed in the Department of Agricultural Chemistry, BAU during November, 2014 to April, 2015. Considering macro nutrient content, the highest values of N, P, K and S were found in the accession AC 10062 whereas Ca and Mg contents were found highest in Bangladeshi variety Cardinal and USA accessions AC 10073, respectively. In case of micro nutrient, the maximum amounts of Cu, Mn, B and Zn were observed in accession AC 10110, AC 10069, AC 10073 and AC 10109, respectively. Significant positive correlations were observed between N-P, N-K and K-Mn contents while K-Mg, Mn-B and Cu-B contents were negatively correlated. Considering all the parameters studied, the USA accession AC 10062, AC 10069 and AC 10110 were nutritionally superior to Bangladeshi variety Diamant and Cardinal. The accession AC 10062 was found as the best USA accession to produce nutrient rich potato in Bangladesh.J. Bangladesh Agril. Univ. 13(2): 207-214, December 2015

“…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.

“…Based on the DIC, Model 4 was the best-fitting model; a multivariate model with unstructured (co)variance matrices for both individual Table 2. A study by Haynes et al (2012) on S. tuberosum ´ (S. phureja-S. stenotomum) 4´-2´ clones found significant levels of genetic variation for a number of micronutrients and a GEI for Zn. and dry matter content (DM, %) in the first and second generations (G 1 and G 2 , respectively).…”

Genetic Evaluation of Micronutrient Traits in Diploid Potato from a Base Population of Andean Landrace Cultivars

Micronutrient malnutrition is a global health problem. An improved understanding of the genetic variation of important micronutrient traits within a potato breeding population will help devise breeding strategies for the biofortification of this important food staple. The dataset consisted of 556 individuals from 17 full‐sib diploid families grown in 2006 in Huanuco, Peru, and 1329 individuals from 32 full‐sib families grown in 2009 in Ayacucho, Peru. Genetic parameters were estimated using univariate and multivariate individual Bayesian models for micronutrient tuber content including Fe and Zn. Genetic variance was additive and heritability estimates were moderate (0.36 to 0.57) and inflated if the common environment of full‐sibs was not taken into account. Posterior modes of genetic correlation estimates between minerals, when analyzed on a dry‐weight basis, were all positive (0.04 to 0.72) and between minerals and tuber dry matter were negative (−0.14 to −0.38). On a fresh‐weight basis, genetic correlations between minerals and tuber dry matter were small but positive (0.05 to 0.18). The implications and challenges for selective breeding to enhance micronutrient content in potato tubers are discussed.
