Late blight caused by (Montagne, Bary) is a devastating disease of tomato worldwide. There are three known major genes, , , and , conferring resistance to late blight. In addition to these three genes, it is also believed that there are additional factors or quantitative trait loci (QTL) conferring resistance to late blight.
