Fig. 3From: Genome-wide association mapping and Identification of candidate genes for fatty acid composition in Brassica napus L. using SNP markersManhattan plots of marker-trait association analysis using the PCA + K model for the fatty acid composition of 520 accessions in 2013Cq and 2014Cq. a and b palmitic acid; c and d stearic acid; e and f oleic acid; g and h linoleic acid; i and j linolenic acid; k and l eicosenoic acid; and (m and n) erucic acid. Cq indicates the growing region, Chongqing, China. The dashed horizontal line represents the Bonferroni-adjusted significance threshold (P < 8.8 × 10−5)Back to article page
