Linoleic acid (C18:2) is an important polyunsaturated fatty acid in the seed oil of many crops. Here, we report that mutations in the promoter, intron and CDS of the  FAD2  genes  SalFAD2 . LIA 1 and  SalFAD 2. LIA 2 generate three alleles  LIA   1 a  ,  LIA    1b   and  lia    1   and two alleles  LIA   2  and  lia   2 , respectively, controlling the C18:2 variation (4.4–32.7%) in yellow mustard. The allelic effect on increasing C18:2 content is  LIA    1a   >  LIA    1b   >  lia    1  ,  LIA   2  >  lia   2 , and  LIA    1a   >  LIA   2 . The five  FAD   2  alleles each contain two exons, one intron and a promoter adjacent to exon 1.  LIA   1 a   has a 1152 bp CDS, a 1221 bp intron with promoter function and a 607 bp promoter. Compared with  LIA    1a  , the intron of  LIA    1b   has reduced promoter activity and that of  LIA   2  and  lia   2  has no promoter function due to extensive SNP and indel mutations.  lia   1  differed from  LIA   1 b   by having an insertion of 1223 bp retrotransposon in its intron.  lia    2   with mutations in the promoter has reduced promoter activity compared with  LIA    2  . This study revealed that complex quantitative variation of trait phenotype in plants could be modulated by multiple alleles of oligogenic loci resulting from mutations in the regulatory region and CDS.
