BRASSICA OLERACEA PLANTS WITH A RESISTANCE TO MYCOSPHAERELLA BRASSICICOLA

摘要

The present invention relates to Brassica oleracea plants with a resistance gene to Mycosphaerella brassicicola. The invention also relates to a method for providing a Brassica oleracea plant with a resistance to Mycosphaerella brassicicola, comprising of (a) providing a first B. oleracea plant, which plant comprises a resistance gene to M. brassicicola; (b) crossing the resistant plant with a susceptible second B. oleracea plant; (c) isolating from the progeny genomic DNA 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).
