Resistance to Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape) induced by Leptosphaeria biglobosa and chemical defence activators in field and controlled environments
Effects of pretreatment of Brassica napus leaves with ascospores of Leptosphaeria biglobosa or chemical defence activators [acibenzolar-S-methyl (ASM) or menadione sodium bisulphite (MSB)] on infection by ascospores of ...
Temperature and leaf wetness duration affect phenotypic expression of Rlm6-mediated resistance to Leptosphaeria maculans in Brassica napus
Near-isogenic Brassica napus lines carrying/lacking resistance gene Rlm6 were used to investigate the effects of temperature and leaf wetness duration on phenotypic expression of Rlm6-mediated resistance. Leaves were ...
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
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 ...
Effects of temperature on R1m6-mediated resistance to Leptosphaeria maculans in Brassica napus
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 ...
