Sunflower Verticillium wilt (SVW) is a vascular disease caused by the root infection of Verticillium dahliae.The sunflower (Helianthus annuus L.) leaves become yellow or die when it is seriously infected.Therefore,SVW is a serious threat to the yield and quality.However,chemical and agronomic measures for controlling the disease are not very effective.The selection of more resistant genotypes is a desirable strategy to reduce contamination.A deeper knowledge of molecular mechanisms and the genetic basis of sunflower underlying Verticillium wilt are necessary to speed up in breeding progress.
