Selecting zinc-efficient cereal genotypes for soils of low zinc status locations
Aims

To present options for increasing zinc efficiency of cereals through breeding.

Key messages
  • A critical level of zinc is required in the soil before roots will either grow into it or function effectively.
  •  It is likely that this requirement is frequently not met in deep sandy in fertile soils.
  • This paper presents arguments for breeding cereal varieties with root system is better able to mobilise zink from soil sources of low availability.
  • Significant genetic variation for this character is described for wheat, barley and oats.
  • Linkage to other efficiency traits for example manganese, is poor suggesting independent mechanisms and genetic control not linked to gross root system geometry.
  • Zinc efficiency traits for sandy and clay soils are appear be genetically different.
  •  Zinc inefficient genotypes absorb more zinc from deficient soils.
