Effect of genotype, flesh colour and environment on the glycoalkaloid content in potato tubers from integrated agriculture

Popis výsledku v původním jazyce

The main aim of the study was the evaluation of the content of alpha-solanine, alpha-chaconine and total glycoalkaloids (TGA) in fourteen new potato cultivars with purple and red flesh in comparison with yellow- and white-fleshed control potatoes cultivated in a friendly way in integrated agriculture. The results were obtained from three-year trials on two locations. TGA levels in tubers flesh ranged from 33,69 to 167,77 mg/kg fresh matter (FM), and the ratio of alpha-chaconine to alpha-solanine from 1,18 to 3,78. No TGA safety limit was exceeded for any cultivar. The glycoalkaloids content was not significantly influenced by flesh colour, whereas the cultivar genotype had a decisive influence on their content. Eight cultivars with coloured flesh yielded a more favourable lower TGA content in comparison with the yellow-fleshed control cv. Agria (86,3 mg/kg FM). On the contrary, six cultivars showed higher TGA values. The highest average TGA content was found in the purple-fleshed Bora Valley cultivar
