DIFFERENTIAL yield responses of varieties of 2,4-D tolerant crops have been reported frequently (1, 2, 4). Wide variation in response of Canada thistle (Cirsium anense (L.) Scop.) ecotypes or strains to 2,4-dichlorophenoxyacetic acid (2,4-D) and 3 amino-l,2,4-triazole (amitrole) treatments have been observed. Wiebe (6) reported that tolerance and susceptibility to dichlorodiphenyltrichloroethane (DDT) spray was conditioned by a single gene difference in certain barley varieties. This observation was confirmed in the field at Bozeman (Figure 1). Grogan et al. (2) determined that the reaction
