Frequency distribution of stem rust infection response of the Carberry/AC Cadillac doubled haploid (DH) population. Measurements of Ug99 stem rust reaction made in field nurseries near Njoro, Kenya in 2009 and of North American races near Swift Current, Canada in 2011 are presented. In Kenya, AC Cadillac infection response varied from R-MR to M and Carberry expressed infection response from M to MS-S whereas in Canada, AC Cadillac showed an MR infection response while Carberry showed R-MR
