“…A further important quality criterion arises from the requirements of the food processing industry, which produces chips, French fries and other deep fried products from potatoes. This criterion is the tuber content of the reducing sugars fructose and glucose, which determines the culinary quality of chips and French fries (Brown et al 1990; Hayes and Thill 2002; Kirkman 2007; Mackay et al 1990; Xiong et al 2002). Reducing sugars undergo with amino acids at high temperatures a non-enzymatic Maillard reaction, which results, depending on the amount of reducing sugars in the tubers, in unacceptable dark colored products (Talburt et al 1975).…”

Tuber yield, starch content, starch yield and chip color are complex traits that are important for industrial uses and food processing of potato. Chip color depends on the quantity of reducing sugars glucose and fructose in the tubers, which are generated by starch degradation. Reducing sugars accumulate when tubers are stored at low temperatures. Early and efficient selection of cultivars with superior yield, starch yield and chip color is hampered by the fact that reliable phenotypic selection requires multiple year and location trials. Application of DNA-based markers early in the breeding cycle, which are diagnostic for superior alleles of genes that control natural variation of tuber quality, will reduce the number of clones to be evaluated in field trials. Association mapping using genes functional in carbohydrate metabolism as markers has discovered alleles of invertases and starch phosphorylases that are associated with tuber quality traits. Here, we report on new DNA variants at loci encoding ADP-glucose pyrophosphorylase and the invertase Pain-1, which are associated with positive or negative effect with chip color, tuber starch content and starch yield. Marker-assisted selection (MAS) and marker validation were performed in tetraploid breeding populations, using various combinations of 11 allele-specific markers associated with tuber quality traits. To facilitate MAS, user-friendly PCR assays were developed for specific candidate gene alleles. In a multi-parental population of advanced breeding clones, genotypes were selected for having different combinations of five positive and the corresponding negative marker alleles. Genotypes combining five positive marker alleles performed on average better than genotypes with four negative alleles and one positive allele. When tested individually, seven of eight markers showed an effect on at least one quality trait. The direction of effect was as expected. Combinations of two to three marker alleles were identified that significantly improved average chip quality after cold storage and tuber starch content. In F1 progeny of a single-cross combination, MAS with six markers did not give the expected result. Reasons and implications for MAS in potato are discussed.Electronic supplementary materialThe online version of this article (doi:10.1007/s00122-012-2035-z) contains supplementary material, which is available to authorized users.

“…Since the 1970s and 1980s, potato breeding companies have specialised and consequently their gene pools have increasingly diversified. Currently, cultivars are developed for specific markets such as the processing industry (pre-baked frozen fries, crisps and flakes), fresh consumption (domestic and export markets) or the starch industry, each with their own specific requirements (Kirkman 2007).…”

Phenotypic Analyses of Multi-Environment Data for Two Diverse Tetraploid Potato Collections: Comparing an Academic Panel with an Industrial Panel

Phenotypic analyses of two different association panels of tetraploid potato cultivars are presented. Association panels are sets of variously related genotypes assembled for association analysis purposes. The aims of this research were to inspect, analyse and compare two phenotypic data sets, a first step in association mapping analysis. Variance components for genotypic main effects and genotype-by-environment interactions were calculated, and estimates for the random genotypic main effects were produced. The genotypic main effects for 19 agro-morphological and quality traits were used to study trait by trait correlations within each panel. In addition, for the genotypes shared by both panels, the correlation of genetic main effects between the panels was investigated. The heritability of all traits was high and no large differences were observed between panels. Coefficients of trait variation were highly correlated (r=0.9) for both panels and trait by trait correlations in both panels showed highly similar patterns. These results demonstrate that a single-year balanced field trial as well as using breeders' records yields robust phenotypic information that can be used in a genome-wide association study. Issues related to data management and definition of traits are discussed.

“…The commercial value of potatoes is increased considerably when they are processed into edible products that appeal to consumers on flavor, texture, appearance, and most of all convenience (Kirkman, 2007). Today the major processed products are potato crisps (chips), French fries, and other frozen products, followed by dehydrated products, chilled-peeled potatoes and canned potatoes.…”

“…Industrial production of crisps (chips) started in the 1920s and French fries in the 1950s, and potato processing has since grown into a global industry which is still expanding. In North America and some European countries between 50 and 60% of the crop is processed (Li et al, 2006;Kirkman, 2007). Furthermore, processors are building factories in countries where the potato is primarily grown as a staple food, and this is a trend that is likely to continue.…”
