The use of a zinc-efficient wheat cultivar as an adaptation to calcareous subsoil locations
Aims

To compare the zinc efficiency, root growth and production characteristics of 2 cultivars of wheat

Key messages
  • Zinc efficient and inefficient wheat cultivars were grown in soil cores in the glasshouse.
  •  The calcareous soil had low micronutrient levels and high pH and boron.
  • Although cultivar Gatcher produced 47% more dry weight of tops and double the root length density of cultivar Excalibur at maturity, cultivar Excalibur was much more efficient in terms of zinc uptake by roots and sevenfold more efficient than cultivar Gatcher in partitioning zinc to grain.
