1Genetic diversity for grain Zn concentration in finger millet genotypes:Potential for improving human Zn nutrition显示文摘Nearly half of the world population suffers from micronutrient malnutrition,particularly Zn deficiency.It is important to understand genetic variation for uptake and translocation behaviors of Zn in relevant crop species to increase Zn concentration in edible parts.In the present study,genetic variation in grain Zn concentration of 319 finger millet genotypes was assessed.Large genetic variation was found among the genotypes,with concentrations ranging from 10 to 86 μg g^(-1)grain.Uptake 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 translocation.Genotypes GEC164 and GEC543 showed increased grain Zn concentration.Genotypes GEC331 and GEC164 also showed improved yield under Zn treatment.Appreciable variation in grain Zn concentration among finger millet genotypes found in this study offers opportunities to improve Zn nutrition through breeding.Ramegowda Yamunarani Geetha Govind Venkategowda Ramegowda Harshavardhan Vokkaliga Thammegowda Shankar Ambarahalli Guligowda 2016The Crop Journal2016,4,3:1
