COMPARISONS OF HIGH YIELDING GENETICALLY DIVERSE WHEAT LINES IN CROATIA

Wheat is one of the most common and important cereals in Croatia. Therefore, high selection pressure at wheat breeding program is continually placed on disease, drought and lodging resistance, heading date and end-use quality. The usage of genetically resistant wheat lines to abiotic and abiotic stresses can be useful in controlling of wheat diseases and food contamination. The aim of the current study was to evaluate the wheat grain productivity and quality, as well as response of wheat seedlings to drought. In the current study, five lines of winter wheat with referent variety were used for evaluation of desired traits. In general, investigated wheat lines had such good characters as early maturity, high yield, but they were smaller in test weight and protein content, but with higher sedimentation value, dough energy and extensibility, compared to referent variety Kraljica. Overall, lines Osk.4.330/6-18, Osk.3.530/59-18, Osk.4.354/12-18 out yielded the referent check with regard to the grain yield. According to the results collected in this research, wheat lines differences in germination energy, and seedling growth affected by drought were obtained. As planting conditions are not always ideal, all lines could offer farmers tolerance to mild drought during sowing, and will achieve high yields. Nevertheless, stability and drought tolerance of investigated winter wheat lines at different environments needs to be checked at multi- location trials.
