The individual plants of the remaining 25 varieties were somewhat 
variable in response to rust inoculation. This is shown in Table VI. 
In the varieties Blue Pod Navy, Yellow Eye, Lady Washington, White 
Marrow, and Bird Eye, a large percentage of the individuals developed 
sori and a small percentage showed no infection, while these conditions 
were reversed in Lazy Wife. There were no intermediate or flecking 
plants in any of these.
