Inheritance of Spotted Wilt Resistance in the Tomato II. Five Genes Controlling Spotted Wilt Resistance in Four Tomato Types

Abstract

The four spotted-wilt-resistant tomato types, Lycopersicon pimpinellifolium and L. esculentum varieties Rey de los Tempranos, Pearl Harbour, and Manzana, were each crossed with the susceptible variety Potentate, and also crossed with each other in all possible combinations. The F 1 and F 2 plants, when inoculated with 10 strains of tomato spotted wilt virus, were resistant to five groups of these strains.
