Abstract
Relevance. Broomrape (Orobanche cumana Wallr.) is one of the major limitations in sunflower production in most countries, cultivating it.
Results. The analysis of the racial belonging of broomrape seeds collected in 2019 from different fields of the Rostov, Voronezh, Belgorod regions and the Krasnodar Territory of the Russian Federation showed their marked heterogeneity in virulence. In these regions, there are still fields where race E dominates, but with an admixture of highly virulent biotype G. There are fields with domination race F or G. Of the 7 samples of broomrape seeds collected in the Rostov region, three showed the presence of race H, as well as all samples from the Voronezh region and one from the Krasnodar Territory. n the samples of seeds from the Belgorod region, race H was not detected. Monitoring of the racial belonging of broomrape seeds from different fields is still relevant for their use in sunflower breeding for immunity and proper placement of a cultivated assortment that can slow down the race formation in a particular field.
