Temperature affects the effectiveness of R gene mediated resistance against Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape)
(2014)
Phoma stem canker (Leptosphaeria maculans) is an economically important disease on oilseed rape (Brassica napus) in Europe, Australia and North America. Effective control of this disease relies on the use of two types of ...
Understanding interactions between quantitative resistance and qualitative resistance for sustainable management of Phoma stem canker (Leptosphaeria maculans ) in oilseed rape (Brassica napus)
(2013-08)
Effective control of phoma stem canker (Leptosphaeria maculans) relies on use of host resistance. Two types of resistance to L. maculans have been identified; major resistance (R) gene-mediated qualitative resistance and ...
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 ...
Comparative epidemiology of Leptosphaeria maculans and L. biglobosa on oilseed rape in the UK
(2013-08)
Phoma stem canker is a major disease problem on winter oilseed rape (Brassica napus) in the UK. The disease is caused by two closely related species, Leptosphaeria maculans and L. biglobosa. Previous epidemiology work has ...
Geographic variation in Leptosphaeria maculans (phoma stem canker of oilseed rape) populations in the UK
(2013-08)
Major resistance (R) gene-mediated resistance against Leptosphaeria maculans is associated with a gene-forgene interaction in which the product of a pathogen effector (Avr) gene is recognised by the product of a host R ...
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. ...
The race structure of Leptosphaeria maculans (phoma stem canker) in the United Kingdom
(INRAE, 2012-10)
Phoma stem canker (Leptosphaeria maculans) is the main disease problem on winter oilseed rape (Brassica napus) in the UK, causing losses of > £100M p.a., despite use of fungicides. Two types of resistance to L. maculans ...
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 ...
