Chickpea genotypes differ in their sensitivity to zinc deficiency locations
Aims

To compare chickpea genotypes for their susceptibility to zinc deficiency and to identify some plant characteristics that are related to zinc efficiency in different genotypes.

Key messages
  • Response of 13 chickpea genotypes to zinc nutrition was studied in a pot experiment under glasshouse conditions.
  • When grown with no added zinc, zinc deficiency symptoms appeared 3–4 weeks after planting.
  • Zinc efficiency based on shoot dry weight showed marked differences among genotypes.
  • Root:shoot ratio was increased and proportionally more zinc was transported to the shoot when the soil was deficient.
  • Cultivars that were very sensitive to zinc deficiency tended to have their root:shoot ratio increased by zinc deficiency more than less sensitive cultivars.
  • The insensitive lines transported more than 70% of the total absorbed zinc to the shoot .
  • Chickpea genotypes vary in their sensitivity to zinc deficiency.
