Fitness cost associated with loss of the AvrLm4 avirulence function in Leptosphaeria maculans (Phoma stem canker of oilseed rape)
(2006-01)
Near-isogenic isolates of Leptosphaeria maculans differing at the AvrLm4 avirulence locus (AvrLm4 or avrLm4) were produced in vitro. Methods for inoculation of leaves of oilseed rape with ascospores or conidia were compared. ...
OREGIN collection of oilseed rape fungal pathogen isolates managed by a relational database accessible to stakeholders via the Internet
(IOBC, 2006)
One aim of the Defra-funded Oilseed Rape Genetic Improvement Network (OREGIN) is to establish, characterise and catalogue a collection of Leptosphaeria maculans (phoma stem canker) and Pyrenopeziza brassicae (light leaf ...
Prediction of the date of onset of phoma leaf spot epidemics on oilseed rape in the UK
(IOBC, 2006)
To reduce reliance on fungicides for control of oilseed rape diseases, Decision Support Systems (DSS) are being developed to target applications as part of an integrated disease management strategy. This paper reports on ...
Effects of temperature on R1m6-mediated resistance to Leptosphaeria maculans in Brassica napus
(IOBC, 2006)
Near-isogenic lines of Brassica napus lines with/without the resistance gene Rlm6 were used to investigate the effects of temperature on Rlm6-mediated resistance to Leptosphaeria maculans. Leaves were inoculated with ...
Development of light leaf spot and phoma stem canker on a range of current and historical oilseed rape cultivars at Rothamsted in 2003/4 and 2004/5 growing seasons
(IOBC, 2006)
Field trials in successive growing seasons (2003/04 and 2004/05) were monitored for light leaf spot (Pyrenopeziza brassicae), phoma leaf spot and phoma stem canker (Leptosphaeria maculans) infection. Each experiment included ...
In vitro mutation and selection of doubled-haploid Brassica napus lines with improved resistance to Sclerotinia sclerotiorum
(2005-06)
This paper describes a new protocol to develop doubled-haploid (DH) Brassica napus lines with improved resistance to Sclerotinia sclerotiorum. In this protocol, haploid seedlings derived from microspore cultures of B. napus ...
Pest and disease management system for supporting winter oilseed rape decisions (PASSWORD) – validation phase
(HGCA, 2005)
Pests and particularly diseases cause serious loss of yield and quality in winter oilseed rape estimated to exceed £80 million/annum in some years. These losses have occurred despite an annual expenditure of about £3.5 ...
Resistance to Leptosphaeria maculans in Brassica napus (oilseed rape) leaves (phoma leaf spot) and stems (canker)
(British Crop Protection Council, 2005)
Use of risk prediction models for integrated control of diseases of oilseed rape in the UK
(British Crop Protection Council, 2005)
Development of a decision support system for phoma and light leaf spot in winter oilseed rape (PASSWORD project)
(HGCA, 2004-12-14)
Pests and diseases in winter oilseed rape cause serious loss of yield and quality. Losses, predominantly from diseases, are estimated to exceed £80 million/annum in some years. These losses have occurred despite an annual ...
