Pathogenicity of leptosphaeria maculans isolates obtained from brassica napus (oilseed rape) cultivars with the rlm7 resistance gene
(2013-08)
Isolates obtained from winter oilseed rape cultivars with the resistance gene Rlm7 were examined for their pathogenicity by inoculation onto cotyledons and true leaves of the susceptible cultivar Drakkar (no R gene) and ...
Pathogenicity of Leptosphaeria biglobosa to oilseed rape (Brassica napus) cultivars differing in resistance against Leptosphaeria maculans
(2013-08)
Field and controlled environment experiments were done to examine the pathogenicity of L. biglobosa on cultivars with good resistance (carrying the Rlm7 gene) or moderate resistance (carrying the Rlm4 gene) against L. ...
Analysing virulent and avirulent Leptosphaeria maculans isolates to understand R gene-mediated resistance in Brassica napus
(2012-10)
Phoma stem canker (Leptosphaeria maculans) is a major disease on oilseed rape (Brassica napus) in Europe (e.g. it causes losses to UK farmers of > £100M p.a.). Single major gene resistance (R) in B. napus against L. maculans ...
