Conservation of “oca” varieties, Oxalis tuberosa Molina, an Andean tuber at risk of genetic erosion: genetic and bromatological diversity in ex situ germplasm collections and promotion of quasi in situ conservation in indigenous communities

General Objective: Contribute to the ex situ and quasi in situ conservation of Oxalis tuberosa, “oca”, a tuber from the Andes in danger of genetic erosion, through the study of its genetic diversity, its bromatology and its importance for local agrobiodiversity.

Specific objectives

  • Analyze the structure and genetic diversity of ocas present in the country's germplasm banks using the Genotyping-by-Sequencing (GBS) technique.
  • Characterize the bromatological composition of oca varieties in the country through analysis of sugar, protein, macronutrient, micronutrient and vitamin content.
  • Evaluate the agricultural importance of agrobiodiversity, including the relative importance of oca cultivation, in the indigenous communities of the Cotacachi canton.
  • Train Ecuadorian human talent in the area of ​​in situ, ex situ and quasi in situ conservation of agrobiodiversity, through continuous training in agrobiodiversity issues and its genotypic and phenotypic expressions.
