Determinacion del contenido de minerales en 44 genotipos de papas nativas de Jujuy

Abstract

The mineral content, vitamin C, and chlorogenic acid were determined in 44 genotypes of Andean potatoes reintroduced in the Quebrada de Humahuaca, Jujuy, Argentina. This initiative aims to promote biodiversity and support local producers by determining the nutritional and functional properties of these genotypes. The genotypes from a collection in the Germplasm Bank of INTA Balcarce, were planted in sandy clay loam soils and harvested manually. The tubers obtained showed significant variability in size, even within the same genotype. The maximum yield was 0.60 kg/plant, with the CL 621 genotype having the highest yield. Genotype CL836 stands up for its high content of Mg, Ca, and Zn (190.3 ± 10.5; 112.2 ± 1.9; 1.29 ± 0.12 mg/100 g dw, respectively); CL 790 for its Mn content (2.09 ± 0.048 mg/100 g dw), and CL 516 and CCS 1349 are rich in Zn and Ca (2.23 ± 0.08 and 123.11 ± 6.88 mg/100 g dw) respectively. The highest contents of Vitamin C and chlorogenic acid corresponded to the CCS1385 and CL 631 genotypes (17.62 ± 0.11; 91.64 ± 1.82 mg/100 g dw) respectively. According to the correlation analysis, the highest content of antioxidants was in small tubers. This information will allow promoting the cultivation of genotypes that contribute to the nutritional security of the local population.
