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 ...
Combining R gene and quantitative resistance increases effectiveness of cultivar resistance against Leptosphaeria maculans in Brassica napus in different environments : Combining R gene and quantitative resistance against Leptosphaeria maculans
Using cultivar resistance against pathogens is one of the most economical and environmentally friendly methods for control of crop diseases. However, cultivar resistance can be easily rendered ineffective due to changes ...
Azole sensitivity in Leptosphaeria pathogens of oilseed rape: the role of lanosterol 14α-demethylase
Lanosterol 14-α demethy lase is a key enzyme intermediating the biosynthesis of ergosterol in fungi, and the target of azole fungicides. Studies have suggested that Leptosphaeria maculans and L. biglobosa, the causal ...
Incorporating pleiotropic quantitative trait loci in dissection of complex traits: seed yield in rapeseed as an example
Most agronomic traits of interest for crop improvement (including seed yield) are highly complex quantitative traits controlled by numerous genetic loci, which brings challenges for comprehensively capturing associated ...
Evaluation of oilseed rape seed yield losses caused by Leptosphaeria biglobosa in central China
Phoma stem canker of oilseed rape (Brassica napus), caused by Leptosphaeria maculans/L. biglobosa is a globally important disease. Severe phoma stem canker symptoms have been observed on winter oilseed rape in China but ...
Effects of a penthiopyrad and picoxystrobin fungicide mixtureon phoma stem canker (Leptosphaeria spp.) on UK winteroilseed rape
In the UK, fungicides are often used to controlphoma stem canker on winter oilseed rape. Field trialswere established near Boxworth, Cambridgeshire for fourcropping seasons (2011/2012, 2012/2013, 2013/2014 and2014/15) to ...
Identification of environmentally stable QTL for resistance against Leptosphaeria maculans in oilseed rape (Brassica napus)
Phoma stem canker, caused by Leptosphaeria maculans, is a disease of world-wide importance on oilseed rape (Brassica napus). Quantitative trait locus (QTL) mediated resistance against L. maculans in B. napus is considered ...
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 ...
Leptosphaeria spp., phoma stem canker and potential spread of L. maculans on oilseed rape crops in China : 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 in central China (in May) than on spring oilseed rape in north China (in August). ...
