ENVIRONMENTAL AND GENETICAL INFLUENCES ON NUTRITIONAL STATUS OF WHEAT GRAIN

Seven domestic cultivars of winter wheat developed in Institute of Field and Vegetable Crops (Evropa, Milica, Renesansa, Tera, NS–rana 5, PobedaandJarebica) were grown on Novi Sad (chernozem) and Kragujevac (dedegraded vertisol) experimental fields for the 2004/05–growing season. Wheat grain under conditions of Kragujevac vertisol contained considerably higher N (+26%), Ca (+13%), Fe (+32%) Cu (+64%), Zn (+2.6 fold) and Cd (+2.5 fold) compared to wheat on Novi Sad chernozem. Also, with exception of Mg, significant differences of wheat grain composition among the cultivars were found. For example, the cultivarEvropacharacterized with the lowest contents of N, P, Ca, Fe and Cu. The cultivarMilicahad the highest Fe and Ni contents, the lowest Mn as well. The cultivarRenesansahad the highest K, Ca, Cu and Zn, and the lowest Ni contents. The highest Mn contents in grain of theTeraandPobedawere found. Additionaly, thePobedahas the highest N and Mn, as well the lowest Zn contents. TheRenesansaandNS rana 5have the highest K contents in grain. Specifities of theTeraandJarebicawere the highest Mn and the lowest K, respectively.
