The potato R locus is necessary for the production of red pelargonidin-based anthocyanin pigments in any tissue of the plant, including tuber skin and flower petals. The production of pelargonidins in plants requires the activity of dihydroflavonol 4-reductase (DFR) to catalyze the reduction of dihydrokaempferol into leucopelargonidin. To test the(More)
In Chile, potatoes are grown in a wide range of ecological zones and levels of technology resulting in wide ranges of crop management and yields. The aim of the present study was to assess yield gaps, resource use efficiencies and foot-printing in different potato cropping zones between 18 and 53° South considering early and late crops, small and large(More)
Chile is the origin of the Solanum tuberosum group Chilotanum corresponding to lowland tetraploid landraces. The most complete morphological description of the Chilean germplasm was published in 2008 in the Catalogue of Varieties of Native Potatoes from Chile, which describes 211 varieties. Two institutions of the Chilean government, INIA and SAG(More)
The objective of the analysis was to calculate the attainable CO2 emissions associated with the production of one ton of potatoes in a high yield environment in southern Chile. Two field experiments were performed. The first field experiment used an optimal sowing date while the second experiment used a late sowing date. In each experiment, treatments were(More)
