According to the results of researches between 2015-2019 years, to create the initial lines of sunflower hybrids, resistant to hybrids of the imidazolinone and sulfonylurea classes were 10 thousand crossings of maternal and paternal forms on the fertile basis with subsequent individual selection and identified: maternal form CB258a and paternal form CB215b-for hybrids class of imidazolinones: maternal form CLEO-123 and paternal forms SP 1459 - for sulfonylurea class hybrids, hybrid combinations with which provide herbicide-resistant hybrids of sunflowers. The relevance of the work is due to the demand of the agricultural market in creating baselines of domestic special-purpose hybrids that are adaptive to weather and climate conditions and soil and environmental factors of zero treatments, when the use of herbicides is mandatory and a decrease in the pesticide load is implied.
