Marker SNPs associated with texture in tubers of phureja

Guateque A., Restrepo L.P., Kushalappa, A., Mosquera-Vásquez, T.

Solanum tuberosum, is a specie of the Solanaceae family that grown in different regions of the world. In the Andean region is a staple food in fresh consumption or process (chips and French fries). However mostly of the current potato cultivars does not have the require characteristics in texture quality for the industry, so there is a significant need to improve the quality of potatoes.

Hydroxyccinamic acid-like compounds in Colombian boiled diploid potato genotypes

C-E Narváez-Cuenca, N Tarquino, E Moreno, C-J Piñeros-Niño, T Mosquera-Vasquez

In Colombia, among different cooking methods, potato tuber is mainly consumed in boiled preparations. Phenolic compounds are of interest due to their role in human health. Hydroxycinnamic acid-like compounds (HCA-LC) are the main phenolic compounds in quantity and diversity present in potato tubers [1]. HCA-LC can be classified as non-anthocyanin (non-ACN)-HCA-LC and as ACN-HCA-LC. Chlorogenic acid (ChA), followed by others such as neo-ChA, cryptoChA, and caffeic acid are the main contributors in quantity to the non -ACN-HCA-LC in potato tubers. At the National University of Colombia we have a collection of more than 100 potato genotypes from the Phureja group that have not been characterized for their phenolic composition. The aim of this work was to quantify the aforementioned compounds in 60 boiled Colombian potato genotypes from the Phureja group.

 

Phenolic compounds in raw and boiled yellow Colombian diploid potato genotypes

Potato (Solanum tuberosum) is the third crop in caloric input worldwide and a high potential as a source of secondary metabolites such as the phenolic compound (PC) group. It is known that non-anthocyanin hydroxycinnamic acid-like compounds (non-ACN-HCA-LC) is the main group of PC in yellow potato tubers. Although potato consumption pattern is changing, the main form of usage is boiled in water or similar preparations. Different authors had reported the change in the level of concentration nutritional compounds by boiling effect, which mainly affects phenolic compounds varying the concentration.

Genetic diversity in potato breeding for nutritional quality in Colombia

Clara Piñeros, Alejandra Guateque, Clara Peña, David Cuéllar, Ajjamada Kushalappa, Carlos Narváez, Patricia Restrepo, Teresa Mosquera

Southern Colombia is a diversity center for diploid potato. We are starting a potato breeding program focused on nutritional traits. We are evaluating nutritional quality of potato genotypes and the biochemical analysis includes sugars, proteins, minerals, starch, moisture, fat, dietary fiber and others as antioxidants that includes carotenoids and vitamin C. Chemical analysis also includes antinutritional compounds such as glycoalcaloidsthat are common in potatoes. These results contribute to the selection of optimal genotypes for breeding and consumption.

 

Phenotypic characterization of reducing and non-reducing sugars content in Solanum tuberosum group Phureja

Duarte Diana, Restrepo Patricia, Kushalappa Ajjamada, Mosquera Teresa

Ready-to-eat products present an increasing demand which is reflected in the fast growing of potato processing market. Colombia is an important producer of diploid genotypes, which belong to the culOvated group Phureja and present outstanding organolepOc properOes. Currently, there are not Phureja culOvars suitable for frying processes because of high levels of reducing sugars in the tubers. AssociaOon mapping is a strategy to study the molecular basis of complex traits such as reducing (glucose and fructose) and non-reducing sugars (sucrose, main source of reducing sugars) content, as a first step in the development of diagnosOc molecular markers that can be used by breeders in processes of marker assisted selecOon. The main purpose of this research is to perform the phenotypic characterizaOon of reducing and non-reducing sugar content in a natural populaOon of Solanum tuberosum group Phureja using the HPLC technique, to obtain the phenotypic informaOon to implement an associaOon mapping approach to idenOfy genomic regions related to frying quality. 

 

Novel candidate genes for quantitative resistance to late blight in potato

Teresa Mosquera-Vásquez, María Fernanda Álvarez, José M. Jiménez-Gómez, Astrid Draffehn, Christiane Gebhardt

Late blight continuous to be the most important disease of the potato crop and its chemical control generates high production costs and damage to the environment. The development of new potato cultivars with field resistance to Phytophthora infestans requires the search for variants of those genes that are involved in the quantitative defense response.

Multidisciplinary research to improve global food security of the native Andean communities

Mosquera Teresa, Del Castillo Sara, Cuéllar David, Navia Sonia, Perilla Leonor, Restrepo Patricia, Rodríguez Ernesto, Kushalappa Ajjamada

A comprehensive project involving potato breeding, genomics, metabolomics, biochemistry, human nutrition, gender studies and agricultural education through participative research is in progress to improve the food security of indigenous communities in Colombia. The indigenous populations of Nariño province in Colombia are the second highest undernourished people in Colombia. The project seeks to impact on improved potato cultivars with high yield and nutritional qualities to improve daily diet, to make visible women’s roles as axes of the family, adopt improved nutritional habits, develop participatory research on Good Agricultural and Postharvest Practices, develop nutritional value criteria in breeding processes and select potato genotypes with high resistance to “late blight” to mitigate potential risks of climate change.

 

Diploid potato breeding through participatory selection for food security of indigenous communities in Colombia

Rodríguez, L.E., A. Alba, D.L. Duarte, C.B. Peña, C. Piñeros, L.P. Restrepo, S. Tinjaca, T. Mosquera, A. Kushalappa, S. Navia

The indigenous communities in Nariño are in poverty and their food security is a national concern, 67.7% of the homes in Nariño are in food insecurity. Potato production represents the main economic activity in the Nariño region, especially with smallholder farmers. S. tuberosum Phureja group, is a valuable genetic resource of potato. The area of planted diploid potato in Colombia represents 8 % (10 to 12 thousand ha/year), of total potato area, with high consumer acceptance.

A comprehensive project involving potato breeding, genomics, metabolomics, biochemistry, human nutrition, gender studies and agricultural education through participative research is in progress to contribute to the improvement of the food security of indigenous communities in Colombia. The indigenous populations of the province of Nariño in Colombia are the second highest undernourished people in Colombia. Potato is a staple food crop and the main source of family income. A multidisciplinary research team has been constituted to introduce new methodologies for plant breeding, evaluate nutritional status and develop functional foods, select for potato disease resistance, educate and empower women to achieve food security for the families in Nariño.
