One-step transformation of two Andean potato cultivars (Solanum tuberosum L. subsp. andigena)

Plant Cell Reports, 2001
Most Agrobacterium-mediated transformation procedures described in the literature have proven to be inefficient for transformation of Andean potato cultivars. We describe here a more successful method for transformation of two of these cultivars, Diacol Capiro (DC) and Parda Pastusa (PP).

In Vitro Digestibility and Physicochemical Properties of Isolated Starch from Potatoes (Solanum tuberosum and Solanum subsp. andigena) Varieties Commercialized in the Andean Region: Ecuador

Starch - Stärke, 2022
AbstractStarches from nine potato tubers marketed in Ecuador were evaluated for their in vitro digestibility, morphological, thermal, and pasting properties. Raw starches are resistant to enzymatic hydrolysis, but their digestibility increases significantly after gelatinization. Rapidly digestible starch (RDS) increases from 3.8 to 6.2 folds, while the

Varieties of Solanum tuberosum , subsp. andigena , as a source of resistance to common scab

Australian Journal of Experimental Agriculture and Animal Husbandry, 1962
High resistance to potato scab of two varieties of the tetraploid Solanum tuberosum subspecies andigena has been demonstrated in a replicated trial at Spring Hill in the central tablelands of New South Wales. The use of scab resistant varieties of this subspecies in a breeding programme would present less difficulty than the use of diploid or triploid ...

Chlorogenic acid, anthocyanin and flavan-3-ol biosynthesis in flesh and skin of Andean potato tubers (Solanum tuberosum subsp. andigena)

Food Chemistry, 2017
Natural variation of Andean potato was used to study the biosynthesis of phenolic compounds. Levels of phenolic compounds and corresponding structural gene transcripts were examined in flesh and skin of tubers. Phenolic acids, mainly chlorogenic acid (CGA), represent the major compounds, followed by anthocyanins and flavan-3-ols.
