Plant processes regulating tuber micronutrient concentrations of potato genotypes in different environments
Description:
Goal: The project goal is advancing the understanding of plant processes that regulate Fe and Zn content of potato tubers. This will help to increase micronutrient contents through agronomic intervention and genetic selection, and may contribute to reduce malnutrition among rural populations in low-income countries. Purpose: In current field trials of CIP´s Germplasm Enhancement and Crop Improvement Division in Peru whole plant micronutrient accumulation and micronutrient distribution between haulms and tubers will be measured to assess the roles of acquisition from soil and remobilization within plant for genotypic variation of tuber micronutrient concentrations in different environments. In pot experiments in Lima and Berlin with a few selected genotypes, nutrient supply and haulm senescence will be specifically varied to collect further information about the processes that control tuber micronutrient concentration.
