主　　题：Finger millet Genetic variation Human nutrition Micronutrient Zinc 

摘      要：Nearly half of the world population suffers from micronutrient malnutrition,particularly Zn *** is important to understand genetic variation for uptake and translocation behaviors of Zn in relevant crop species to increase Zn concentration in edible *** the present study,genetic variation in grain Zn concentration of 319 finger millet genotypes was *** genetic variation was found among the genotypes,with concentrations ranging from 10 to 86 μg g^(-1)*** and translocation studies with Zn/^(65) Zn application in 12 selected low-Zn genotypes showed wide variation in root uptake and shoot translocation,with genotypes GEC331 and GEC164 showing greater uptake and *** GEC164 and GEC543 showed increased grain Zn *** GEC331 and GEC164 also showed improved yield under Zn *** variation in grain Zn concentration among finger millet genotypes found in this study offers opportunities to improve Zn nutrition through breeding.
