| Abstract: | Embryogenic cell suspensions were filtered and the globular embryoids and embryogenic aggregates exposed to the herbicide Asulam at a concentration of 8 × 10-5 M in liquid culture for 1 week; the suspension was then plated in an Asulam-free agar medium. The surviving embryoids were allowed to develop into plants which eventually flowered and the seed was collected. Cultures were also re-initiated from the young plants and tested for the presence of Asulam resistance. Undifferentiated and differentiated cell lines were isolated from the selected plantlets and both were shown to be resistant to Asulam. Since the plants did not set viable seed it was not possible to test the progeny. However, the presence of resistance in the tissue cultures derived from the plants developed from selected embryoids suggested the selection procedure involving embryoids, rather than undifferentiated cells, was successful in producing a source of Asulam resistance which was possibly due to a mutation.
