Figure 1. An example of a needle-lesion frequency map of a 

 seedling bed produced by computer: A = no lesions; B = 1-5 

 lesions; C = 6-25 lesions; D = 26-100 lesions; E = 100+ 

 lesions; N = foliage non-readable (dead, dying, or missing) 

 at time of examination; S = no lesions at time of examination: 

 but canker later developed. Note the resistant progeny 

 57 x self.
