Aims

To determine the genotypic variation in oilseed rape to tolerate zinc deficiency and to identify the efficient genotypes.

Key messages
  • Twenty five genotypes of oilseed rape (canola and mustard) were tested under varied supply of zinc in pot experiments in soil culture to determine the genotypic variation in tolerance to the zinc-deficient condition.
  • On the basis of the pot experiments, ten genotypes were tested in 1995 under varied supply of zinc on a zinc-deficient field in South Australia.
  • Zinc efficiency in pot Experiment 1 varied from 35% for 92-13 to 74% for Siren. Narendra, Dunkeld, Barossa, Oscar and Xinza 2 performed well under low zinc conditions zinc efficiency in Experiment 2 varied from 32% for Wuyou 1 to 62% for Pusa Bold.
  • Root dry matter accumulation was significantly higher in zinc-efficient genotypes.
  • With few exceptions, the ranking of genotypes in pot and field experiments indicates similarity in their response to zinc deficiency.
  • Zinc-efficient genotypes had lower zinc concentration in roots and higher zinc concentration in youngest fully opened leaf blades, indicating a better transport of zinc.
  • This, together with a higher zinc uptake, appears to be the basis of expression of zinc efficiency.

Basal fertilizer (128 kg Di-ammonium phosphate ha1) was applied to all the plots at time of sowing; 30 kg N ha1 in the form of urea was applied post emergence. Zinc was applied @ 3.5 kg ha1 in form of zincsol as pre-sowing spray to the soil surface only in +Zn treatment
