Fig. 2From: Multi-environment QTL studies suggest a role for cysteine-rich protein kinase genes in quantitative resistance to blackleg disease in Brassica napus Significant QTL clusters for TC and TS Populations. Linkage maps shown only for B. napus chromosomes harbouring significant QTL (TC: A01, A07, A08 & C06; TS: A01, A07, A09, C06). QTL for survival (green), internal infection (red) and cotyledon (blue) metrics. Single-environment QTL shown as open boxes, multi-environment QTL as solid boxes. Green dotted lines indicate common markers. Positions of blackleg R genes Rlm3 and Rlm4 shown in bold Back to article page
