Inheritance Pattern and Molecular Markers for Resistance to Blackleg Disease in Cabbage.

ABSTRACT: The inheritance and causal loci for resistance to blackleg, a devastating disease of Brassicaceous crops, are yet to be known in cabbage (Brassica oleracea L.). Here, we report the pattern of inheritance and linked molecular marker for this trait. A segregating BC₁ population consisting of 253 plants was raised from resistant and susceptible parents, L29 (♀) and L16 (♂), respectively. Cotyledon resistance bioassay of BC₁ population, measured based on a scale of 0-9 at 12 days after inoculation with Leptosphaeria maculans isolate 03-02 s, revealed the segregation of resistance and ratio, indicative of dominant monogenic control of the trait. Investigation of potential polymorphism in the previously identified differentially expressed genes within the coll
