A test method for resistance to stem mottle in potatoes

In breeding for resistance to stem mottle in potatoes there is a need for a rapid testing and selection method. Following the method normally used with X- and Y-virus, seedlings in the cotyledon stage and young plants of potatoes were inoculated with the stem mottle virus (= rattle virus). In this way it seems possible to test and to select young seedlings for resistance. In addition it is possible to establish rapidly the resistance of known potato varieties and progenitors with the air of young plants.
