|a Two ethylmethanesulfonate (EMS) mutant populations of the semi-winter rapeseed cv. Ningyou7 were constructed with high mutant load, to provide a TILLING platform for functional genomics in Brassica napus, and for introduction of novel allelic variation in rapeseed breeding. Forward genetic screening of mutants from the M2 populations resulted in identification of a large number of novel phenotypes. Reverse genetic screening focused on the potentially multi-paralogous gene FAE1 (fatty acid elongase1), which controls seed erucic acid synthesis in rapeseed. A B. napus BAC library was screened, and loci in a reference mapping population (TNDH) were mapped to conclude that there are two paralogous copies of FAE1, one on each of the B. napus A and C genomes. A new procedure is demonstrated to identify novel mutations in situations where two or more very similar paralogous gene copies exist in a genome. The procedure involves TILLING of single plants, using existing SNPs as a positive control, and is able to distinguish novel mutations based on primer pairs designed to amplify both FAE1 paralogues simultaneously. The procedure was applied to 1344 M2 plants, with 19 mutations identified, of which three were functionally compromised with reduced seed erucic acid content
