“…These studies involved the use of a diploid bi-parental potato mapping population of limited agronomic value (Acharjee et al 2018; Werij 2011). In diploid populations the broad sense heritability of protein content has been estimated between 56 and 66% (Lu et al 2012; Werij 2011). These findings indicate that a moderate proportion of the trait variance can be ascribed to genetic factors within a particular experimental setup.…”

Protein content is a key quality trait for the potato starch industry. The objective of this study was to identify allele-specific quantitative trait loci (QTLs) for tuber protein content in cultivated potato ( Solanum tuberosum L.) at the tetraploid level. We analysed 496 full-sib F 1 clones in a 3-year field trial to dissect the complex genetic architecture of soluble tuber protein content. Genotypic data from a 60K single nucleotide polymorphism (SNP) array was used for SNP dosage scoring, constructing homologue specific linkage maps and assembly of a dense integrated chromosomal linkage map. From the integrated map, probabilistic multi-locus identity-by-descent (IBD) haplotypes (alleles) were estimated and used to detect associations between the IBD haplotypes and the phenotypic trait values. Moderate levels of trait heritability were estimated between 40 and 74% that correspond with previous studies. Our contemporary naive analysis identified potential additive QTLs on chromosomes 2 , 3 , 5 (top arm) and 9 across the years. Moreover, cofactor QTL analysis identified two masked QTLs on chromosomes 1 and 5 (lower arm). The QTLs on chromosomes 2 , 5 (lower arm) and 9 are reported here for the first time. The QTLs that we identified on chromosomes 1 , 3 and 5 (top arm) show overlap with previous studies for protein content in potato. Collectively the naive QTLs explained 12 to 17% of the phenotypic variance. The underlying alleles of the QTLs provided both positive and negative effects on the phenotype. Our work uncovers the complex genetic architecture of this trait and describes potential breeding strategies for improvement. As protein has emerged as a high-value component from industrial potato starch production, the dissection of the genetic architecture and subsequent improvement of this trait by breeding has great economic and environmental relevance.

“…Additionally, Bártová et al () report the extraction and characterisation of proteins from the water coming from potato (of Groups Tuberosum and Phureja) starch production, with Kunitz protease inhibitors as the main representatives of the protein fraction. Then, this type of waste might be used to prevent contamination and increase profits by the obtention of valuable proteins (Lu et al , ). Both proteins and hydrolysates can be used in the food industry due to their antifungals (Bártová et al , ), nutritional, bioactive and technofunctional properties (Waglay et al , ; Mulder et al , ; Contreras et al , ).…”

Summary Potato tubers of Group Phureja have a great relevance in terms of production and consumer acceptance in the Andean countries. However, its proximal characteristics, nutritional value and bioactive compounds have been scarcely known. For the first time, this work aims to give an overview on tubers of Group Phureja characteristics, including research works from 1993 to 2019. When analysing the micronutrients and bioactive analytes, sodium, niacin and carotenoid contents are higher as compared to those of the Group Tuberosum. Likewise, the application of a biorefinery approach for the valorisation of Group Phureja wastes was proposed. These wastes may come from tubers that fail to meet quality parameters or by processing potato products. The possibility of obtaining useful compounds for the food, feed, materials, energy and chemical industries is described. The strategy of valorisation of wastes was focused on the production of starch and proteins, previously reported with important technological properties.
