Phenotypic variation of root-system architecture under high P and low P conditions in potato (Solanum tuberosum L.).

Background: Phosphorus (P) is an essential macronutrient required for plant metabolism and growth. Its acquisition by plants depends on the availability of dissolved P in the rhizosphere and on the characteristics of P uptake mechanisms such as root-system architecture (RSA). Compared to other crops, potato (Solanum tuberosum L.

Evaluation of Wild Potato Germplasm for Tuber Starch Content and Nitrogen Utilization Efficiency.

Potato wild relatives provide a considerable source of variation for important traits in cultivated potato ( L.) breeding. This study evaluates the variation of tuber starch content and nitrogen utilization efficiency (NutE) in wild potato germplasm.

Genotype-Specific Differences in Phosphorus Efficiency of Potato ( L.).

Potato is considered to have a low phosphorus (P) efficiency compared to other crops. Therefore, P fertilization requirements are high. New cultivars with improved P efficiency may contribute to save limited mineral P sources and to reduce eutrophication of surface water bodies.
