Abstract
Experiments were conducted to study the genetic variability of Zn, Fe, Mn and Cu concentration in the shoot of wheat and other cereals. Cultivars of rye showed higher Zn efficiency than the wheats. There was a considerable variability for the four elements between rye and wheat varieties. By utilisation of disomic wheat-rye addition lines it could be demonstrated that the rye chromosomes 2R and 7R may improve the Mn and Fe concentrations of wheat, chromosome 1R the Zn and 5R the Cu, respectively. Even in a particular 4B/5R wheat-rye translocation line the Zn, Fe and Mn concentrations were significantly modified from 5.8 to 6.7, 92 to 171 and 123 to 236 ug/g DW, respectively. Both wheat and rye positively respond to Zn supply in Zn concentration of shoots, although the effect in rye is less pronounced. The average increases in Zn concentration in wheat and rye reached 851 % and 689 %, respectively, and correlated with a subsequent decrease of Cu>Fe>Mn. Among the wheats there were remarkable differences in the uptake of Zn additionally applied. The English variety ‘Avalon’ showed the best Zn utilisation.
