Brassica oleracea plants with a resistance to albugo candida

摘要

The present invention relates to Brassica oleracea plants with a resistance gene to Albugo Candida, the cause of white blister. The invention also relates to a method for providing a Brassica oleracea plant with a resistance to Albugo Candida, comprising of (a) providing a first B. oleracea plant which comprises a resistance gene to A. Candida; (b) crossing the resistant plant with a susceptible second B. oleracea plant; (c) isolating genomic DNA from the progeny for detecting the presence of an introgression with the resistance gene using one or more specific DNA markers linked to the resistance gene; and (d) selecting from the progeny a B. oleracea plant in which the presence of the introgression with the resistance gene has been demonstrated in step (c).
