Fig. 1. Frequency distributions of reaction type scores, rust severity ratings, days to heading, and plant height for the 152 recombinant inbred lines from the cross, Ogle/MAM17-5. Reaction type was recorded based on a 1-to-5 scale, where 1 is highly resistant and 5 is susceptible. Severity was rated based on a 1-to-8 scale in which 1 is 0% leaf area covered by pustules and 8 is approximately 40% or more leaf area covered. Days to heading means days from planting to heading. The values next to the x axis are the upper limit of each category.
