The potential for gene flow between Camelina sativa , a promising edible and industrial oil crop in Canada, and its wild North American relatives C. alyssum , C. microcarpa and C. rumelica subsp. rumelica , was investigated. Sequence analysis of the nuclear ribosomal internal transcribed spacer region ( ITS ) was used to differentiate Camelina species and/or accession‐specific nucleotide markers and identify interspecific F 1 hybrids. ITS analysis identified hybrids in progeny of C. alyssum × C. sativa , C. microcarpa accession 36010 × C. sativa and C. sativa × C. rumelica subsp. rumelica . Seed set on C. alyssum × C. sativa F 1 and F 2 progeny was similar to the parents; few seeds were produced on hybrid progeny of C. microcarpa accession 36010 × C. sativa and C. sativa × C. rumelica subsp. rumelica . The study provided evidence that should the species have sympatric distributions and overlapping flowering periods, gene flow between C. sativa and its wild North American relatives is possible and that it would most likely occur with C. alyssum given the high fertility of the F 1 hybrids recovered.
