摘要：
Corresponding results were obtained with A method for obtaining a plant, in particular a cultivated lettuce plant (L. sativa), with a lasting resistance to a pathogen, in particular Bremia lactucae, comprising of providing one or more specific DNA markers linked to one or more resistance genes, determining the presence of one or more resistance genes in a plant using these DNA markers, subsequently crossing a first plant comprising one or more resistance genes with a second plant comprising one or more resistance genes, and selecting from the progeny a plant in which one or more resistance genes are present by using the DNA markers. The invention further relates to the plants obtained with this method, seeds and progeny of these plants, as well as progeny thereof.
