Evaluation of Phosphorus Efficiency in Cultivated and Wild Potato Genotypes.

ABSTRACT: Phosphorus (P) deficiency is a critical constraint to cultivated potato (Solanum tuberosum L.) production, while wild potato germplasm is known to harbor traits that enhance tolerance to low P conditions. The aim of this study was to evaluate the tolerance to P deficiency in cultivated and wild potato accessions from a genebank to identify interesting germplasm for potato breeding. Therefore, ten wild potato accessions and 30 cultivated varieties were evaluated under high (15 mg L^-1) and low (3 mg L^-1) P regimes for various morphological, physiological, and nutrient uptake traits. Significant genotypic variation was observed across all traits, with notable interspecific differences. While low P generally reduced biomass, several genotypes, particularly S. st
