Increasing the yield of sunflower is inextricably linked with the evaluation of newly created interline hybrids and their components (parental forms) using various methods for assessing their combination ability (CА). Breeding research in this direction includes large material and practical costs when using the developed methods for assessing combination ability (CА) due to its small analytical capabilities. New approaches to the analysis of the productivity of hybrids in practical studies can significantly increase the volume of the analyzed material and evaluate not only for a short period of testing, but also for a long period of time over the years. Purpose is determination of the combination ability of parental forms of sunflower interlinear hybrids to optimize the breeding process. When analyzing the determination of the combination ability of the parental components of sunflower interlinear hybrids, the method of evaluating the CА according to a special scale developed at VNIIMK (Krasnodar, Russia) was used. This method makes it possible to analyze a large number of hybrid combinations and their parental forms and draw appropriate conclusions for further use in the breeding process. The analysis of the obtained results makes it possible to fully evaluate the obtained interline hybrid combinations by years of testing. We analyzed 1736 hybrid combinations involving 212 maternal forms and 1472 combinations involving 209 paternal pollen fertility restorer lines. 75 maternal lines with a high total combination ability (GCА) and 97 paternal forms with this trait were identified. Maternal lines with high combinational ability VKU 110 A, VKU 140 A and SV 55 A are of interest for use in practical breeding. Among the paternal forms are SV 123 V, VKU 400 V and VKU 401 V. The components of hybrid combinations with high specific combination ability (SCА) have been determined. These are lines VKU 414 A, VKU 413 A, SV 31 Rf, SP 1459. Hybrids with high adaptive properties have been identified when growing conditions change, which will make it possible to purposefully conduct practical breeding to maintain high productivity of sunflower hybrids
