Sažetak
In a three-year investigation some quantitative traits of ten winter wheat cultivars were studied under particular agrarian-ecological condition.
The results have confirmed the existence of significant variability of the characteristics depending on the base of inheritance and the effect of ecological factors. The yield of grains is a highly variable character, in regard to which significant diferences were found between cvs. and between years. The highest average grain yield was found in the cv. Liberta (6,217 kg/ha), and the variability coefficient ranged from 28.2 to 36.9. The variability coefficient of the 1000 kernel weight from 7.01 to 15.07 and sedimentation test from 8.8 to 24.3 depended on the genetic factors and only to a lesser extent on environmental conditions. The height of plant was highly variable depending on environmental condition as well as on the genetic conditions. Cvs. Mihelca and Patria had highest plants 80 cm, and lowest check Žitarka 70 cm. The variability coefficient ranged from 20.5 to 28.7. The variability parameters for most important quantitative traits implicate to very suitable reaction to growing under different production conditions for cvs. Patria, Marija and Liberta.
Based on the obtained yields and variability parameters, development of wheat varieties which can meet both criteria: yielding capacity and stability seems to be possible.
