Variability of the breeding traits of sunflower hybrids at application of Eurolightning

The possibility of sunflower hybrids development possessing a high level of resistance to herbicide Eu ro-Lightning, and a different variability of traits valuable for breeding in the agricultural and meteorologycal conditions of cultivation were determined. The agricultural and meteorological conditions of cultivation affected the levels of a hybrid resistance to herbicide Euro-Lightning were ascertained. An analysis of the biometric traits permits to determine a level of resistance of sunflower hybrids to Euro-Lightning application.
