Nutritional contents of advanced breeding clones of Solanum tuberosum group Phureja
Nutritional contents of seven advanced breeding clones (AC) of potato (Solanum tuberosum group Phureja) and two commercial cultivars, Criolla Colombia and Criolla Galeras, of S. tuberosum group Phureja as control were evaluated. Fat, protein, ash, dietary fibre, and mineral contents were determined in whole boiled tubers. The AC-04 had the highest levels of protein (9.7 g/100 g dried weight, DW) and magnesium (107.0 mg /100 g DW) as compared to Criolla Colombia (4.0 g of proetin /100 g of DW and 99.5 mg of magnesium/100 g DW). The highest contents of fat (0.7 g/100 g DW), soluble dietary fibre (4.9 g/100 g DW), and manganese (0.8 mg/100 g DW) were found in AC-09, values that represented 3.9, 1.7, and 1.2 fold increase as compared to Criolla Colombia, respectively, and 3.9, 1.8, and 1.1 fold increase as compared to Criolla Galeras. The AC-51 had the highest content of insoluble dietary fibre (13.8 g/ 100 g DW). Among all genotypes the AC-52 had the highest contents of iron (1.3 fold increase), zinc (1.2 fold increase), and calcium (1.3 fold increase) as compared to Criolla Colombia.

Targeted and untargeted approaches unravel novel candidate genes and diagnostic SNPs for quantitative resistance of the potato (Solanum tuberosum L.) to Phytophthora infestans causing the late blight disease
Results of this study provide new insight into the molecular genetic basis of quantitative resistance in potato, and provide a diagnostic toolbox to identify single nucleotide polymorphisms (SNPs): markers that are associated with maturity corrected resistance (MCR) to late blight, for future breeding applications. The SNPs are strong candidates for: being directly involved in the control of quantitative resistance to late blight uncompromised by late plant maturity; for further functional characterization; and for validation of diagnostic power in different breeding populations and environments. The paper describes a detailed breakdown and assessment of marker-trait associations.

Identification of novel associations of candidate genes with resistance to late blight in Solanum tuberosum Group Phureja
A first association mapping experiment was conducted in Solanum tuberosum Group Phureja germplasm, which identified among 29 candidates two genes associated with quantitative resistance to late blight. Potato crop late blight is caused by the oomycete Phytophthora infestans. Quantitative disease resistance (QDR) can be genetically mapped to understand genetic architecture. Genomic, transcriptomic, and traditional quantitative trait loci (QTL) mapping information are useful to find and validate genes associated with late blight resistance. The results generated in this research enable the design of molecular markers that can be evaluated in potato breeding programs.

Breeding differently : participatory selection and scaling up innovations in Colombia
This research-for-development programme links agriculture and nutrition through a two-stage project. It was conducted within the framework of the projects “SAN-Nariño” and “More Nutritious Potatoes,” and developed and delivered three new potato cultivars: Criolla Dorada, Criolla Ocarina and Criolla Sua Pa. Elements for scaling up the more nutritious potatoes include supply, marketing, demand, and public policies. Men and women farmers improved their capacities for agricultural production and selected the best potato cultivars for agronomic conditions and culinary characteristics. In Colombia, iron deficiencies affect 32% of young children; 43% of the Colombian population have zinc and vitamin A deficiencies.

Adoption croissante de la culture de pommes de terre plus nutritives et résistantes aux maladies en Colombie : profil de projet
Des connaissances scientifiques conjuguées à des pratiques traditionnelles ont mené à la création de trois variétés de pommes de terre à chair jaune très nutritives, résistantes et rentables pour les agriculteurs. Des chercheurs de la Colombie et du Canada travaillent avec des partenaires du secteur public-privé afin d’accroître la production et la consommation de ce produit de base nutritif et entièrement naturel en Colombie et partout dans le monde.

CIFSRF final technical report : Scaling up the production of more nutritious yellow potatoes in Colombia (CIFSRF Phase 2)
The “More Nutritious Potatoes Project” development and implementation of a high quality potato seed production system propelled production of three new cultivars, contributing to food security and nutrition in Colombia. As of March 2018, the estimated area of the Project's cultivars reached 734.1 ha, representing 16% of the total cultivated area of yellow potatoes. The paper reports on outputs, outcomes, and milestones of this successful scaling-up programme which included engagement of potato growers, peasants and indigenous communities, officials from public institutions, academics and other stakeholders at local, regional and national levels.

Escuelas comunitarias de agricultura familiar-ECAF. Una propuesta de formación integral para la transformación social. Guía metodológica.
Starting in 2012 the Universidad Nacional de Colombia and McGill University of Canada have developed social innovations that effectively address problems of food insecurity and nutrition in the Andean region of Nariño, Colombia. The Community Schools of Family Farming (ECAF) methodology promotes social development and capacity building, with a strategy that fosters autonomy in individuals, families and communities. In this methodological guide, the reader will find information about the philosophy that guides this methodology and the technologies developed which have been validated in their capacity to produce change.

A model to promote sustainable social change based on the scaling up of a high-impact technical innovation
This paper reports on an intervention model that incorporates common elements, from the literature, of scaling up, and includes novel such as linking technological and social innovations, with an exit strategy to build sustainable processes and results. The model is based on a trans-disciplinary approach, and leadership, that involves local communities and stakeholders to establish synergies, to give coherence to the whole process, and to build an exit strategy involving territorial dynamics related to the innovation. The model includes a clear definition of the objects, and the process, that should be transformed, and
the specific methodologies to involve local communities and stakeholders, to reach the final target user. The model was applied to develop the project, More Nutritious Potatoes, for scaling up new yellow potatoes varieties with improved agronomic and nutritional attributes.

Scaling up the production of more nutritious yellow potatoes in Colombia : project story
Farmers, breeders and scientists collaborated on the development and selection of three new varieties of yellow potatoes (Criolla Ocarina, Criolla Sua Pa and Criolla Dorada) with higher nutritional content, increased resistance to late blight disease, and higher yields. Building local capacity has been key to the project’s sustainability. This includes a sustainable business model for local production; availability of high-quality seeds which increase crop yields for farmers, as well as creating new jobs and improving the health of Colombian consumers. The project’s Shagras para la vida strategy strengthened a communal ancestral relationship with the land and food production.

Expanding adoption of nutritious, disease-resistant potatoes in Colombia : project profile
A marriage of scientific knowledge and traditional practice has led to development of three highly nutritious, robust, and productive yellow potato varieties. As described in the project brief, the next step is to work with farmers to make these new potato varieties available to millions of Colombian consumers, particularly those living in the most food insecure regions of the country. The goal is to replace up to half of Colombia’s yellow potato production with new varieties. Researchers from Colombia and Canada are working with public and private sector partners to increase production and consumption across Colombia and beyond.

Change story : Shagras for life, from traditional home gardens to ancestral, agroecological and more nutritious shagras
“Shagras for life” focused on three pillars: agroecological food production, retrieval of the community’s alimentation memory, and diet diversity. The impact of Shagras for life became evident in the increase in diet diversity of homes and families. The project methodology boosts the traditional shagra and home garden, integrating agriculture with nutrition and socio-cultural processes and environments that contribute to achieving food security and the right to health.
