Oilseed rape (Brassica napus) resistance to growth of Leptosphaeria maculans in leaves of young plants contributes to quantitative resistance in stems of adult plants : Resistance to growth of Leptosphaeria maculans in leaves of young plants
Key message: One QTL for resistance against Leptosphaeria maculans growth in leaves of young plants in controlled environments overlapped with one QTL detected in adult plants in field experiments The fungal pathogen ...
Effectiveness of Rlm7 resistance against Leptosphaeria maculans (phoma stem canker) in UK winter oilseed rape cultivars
The Rlm7 gene in Brassica napus is an important source of resistance for control of phoma stem canker on oilseed rape caused by the fungus Leptosphaeria maculans. This study shows the first report of L. maculans isolates ...
Factors contributing to the holistic control of strawberry powdery mildew
(Association of Applied Biologists, 2014-11)
Predicting timing of release of ascospores of Leptosphaeria spp. to improve control of phoma stem canker on oilseed rape in the UK
Phoma stem canker is an economically damaging disease of oilseed rape crops, causing an annual loss estimated at more than £87M in the UK at a price of £390/t. It is caused by two related pathogens: Leptosphaeria maculans ...
A systems approach to the control of strawberry powdery mildew
A systems approach to the control of strawberry powdery mildew (Podospheara aphanis) is important, as the disease is never absent from the crop. Work reported here shows that the disease is present in the crop whether new ...
Temperature affects the effectiveness of R gene mediated resistance against Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape)
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 ...
Leptosphaeria spp. and Phoma stem canker on oilseed rape in China
In China, the incidence of phoma stem canker observed in pre-harvest surveys from 2005 to 2012 was greater on winter oilseed rape in provinces along the Yangtze River (in May) than on spring oilseed rape in north China (in ...
Pathogenicity of Leptosphaeria biglobosa to oilseed rape (Brassica napus) cultivars differing in resistance against Leptosphaeria maculans
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. ...
Comparative epidemiology of Leptosphaeria maculans and L. biglobosa on oilseed rape in the UK
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 ...
