| Summary: | Establishing criteria in wheat breeding for increased tolerance to abiotic stress conditions of halomorphic soils (solonetz), that will give economically profitable yields, requires sets of parallel trials in normal and abiotic stress conditions. Such trials, testing parental bread wheat genotypes and their F2 progenies helps to examine the extent to which stress conditions affect yield components and grain yield of wheat, but also to determine the usable genetic variability. The multiyear results of variability of winter wheat genotypes, comparing by the location Kumane (solonetz stress conditions) and Rimski Šančevi (normal conditions on chernozem), have shown that under conditions of stress plant height, number and weight of grains per spike have about 30% lower values than those on black soils. The F2 progenies of crosses of selected parental cultivars was observed and separated that new genetic variability in terms of solonetz reach the level ideotype plants on soils, which gives the best results. |
