Abstract
Sunflower (Helianthus annuus L.) is the third most widely grown oilseed worldwide, the production concentrated in Ukraine, Russia, Argentina, Turkiye, Romania, and USA. Due to global demand for sunflowers, there is an increase in cultivation of sunflowers. Nonetheless, sunflower production is affected by abiotic and biotic stress factors. Particularly, the parasite plant Orobanche and fungus downy mildew are the two major biotic stress factors that could cause serious losses in sunflower production. Various control methods such as chemical, mechanical, biological, cultural, etc. are used to cope with these two problems. Due to the speed proliferation of the two, the traditional methods are insufficient to provide sustainable and environmentally friendly solutions. Therefore, it is necessary to use combinations of classical breeding and genomic approaches to identify genetic bases of resistance and incorporate these into breeding programs to achieve long-term resistance to Orobanche and downy mildew. Genome-wide association studies (GWAS) are powerful methods to detect genomic regions controlling the traits of interest in crops and have not been used extensively for identification of genomic regions controlling Orobanche and downy mildew. In this article, the state of resistance to Orobanche and downy mildew as well as GWAS approach to identification of the genomic regions controlling resistance to both are summarized.
