A total of 25 SNPs significantly associated with C22:1 content were detected by GWAS in two regions(8.54 to 11.04 Mb of A08and 56.05 to 56.47 Mb of C03,respectively)(Fig.2-A and Table S5) .Two peaks,Bn-A08-p12814556 on A08 and Bn-A08-p12660208 on C03,explained respectively 24.85%and 13.38%of total phenotypic variance.The two peaks were respectively386.1 and 240.3 kb away from the key genes BnaA.FAE1.a and BnaC.FAE1.a,demonstrating that the association genetics approach was effective and precise for our natural population.Interestingly,the same peak SNPs were also detected on A08for C16:0,C18:0,C18:1,C18:2,and C20:1,and on C03 for C16:0,C18:1,and C20:1(Fig.1 and Table S5).This finding,with path analysis,indicated that the fatty acid components were controlled by common genetic regions and enzyme systems in the fatty acid synthesis pathway in rapeseed.
