Genetic Dissection of Blackleg Resistance Loci in Rapeseed (Brassica napus L.)
Blackleg disease caused by the heterothallic ascomycete fungus Leptosphaeria maculans (Desm.) Ces. et de Not. (anamorph: Phoma lingam Tode ex Fr.), is the major disease of Brassica crops such as turnip rape (Brassica rapa L. syn. B. campestris; 2n = 2x = 20, genome AA), cabbage (B. oleracea L.; 2n = 2x = 18, genome CC), rapeseed (syn. canola or oilseed rape B. napus L.; 2n = 4x = 38, genome AAC...
متن کاملInduced Resistance to Blackleg (Leptosphaeria maculans) Disease of Canola (Brassica napus) Caused by a Weakly Virulent Isolate of Leptosphaeria biglobosa
Canola (Brassica napus L.) is the second largest cash crop in Canada (4). Blackleg disease, caused by Leptosphaeria maculans (Desmaz.) Ces. & De Not. (anamorph = Phoma lingam (Tode:Fr.) Desmaz.), is one of most economically important diseases of canola (21). In the past decade, canola production has expanded significantly worldwide and interest in the blackleg fungus, particularly its biology, ...
متن کاملGenome-wide Association Study Identifies New Loci for Resistance to Leptosphaeria maculans in Canola
Key message "We identified both quantitative and quantitative resistance loci to Leptosphaeria maculans, a fungal pathogen, causing blackleg disease in canola. Several genome-wide significant associations were detected at known and new loci for blackleg resistance. We further validated statistically significant associations in four genetic mapping populations, demonstrating that GWAS marker loc...
متن کاملA Genome-Wide Association Study Reveals New Loci for Resistance to Clubroot Disease in Brassica napus
Rapeseed (Brassica napus L.) is one of the most important oil crops in the world. However, the yield and quality of rapeseed were largely decreased by clubroot (Plasmodiophora brassicae Woronin). Therefore, it is of great importance for screening more resistant germplasms or genes and improving the resistance to P. brassicae in rapeseed breeding. In this study, a massive resistant identificatio...
متن کاملQTL analysis for diamondback moth resistance in canola (Brassica napus L.)
Diamondback moth (DBM), Plutella xylostella L. is the most injurious defoliage insect pest of canola in Ardabil province of Iran. It occurs annually and causes damage in canola fields. This study was performed to identify QTLs controlling resistance to diamondback moth using SSR and RAPD markers. An F2:4 population of 180 families derived from crossing between cv. ‘SLMO46’ and cv. ‘Quantum’ wer...
