The crosses of Blue Pod Butter, the crimson-flowered va- 

 rieties given in Table Y, have been already discussed in con- 

 nection with Table 5. Only one white-flowered plant appeared 

 among those crosses, and that was in the Fs generation of Blue 

 Pod Butter X Burpee Stringless. No reason for its appearance 

 can be assigned. 



Table 8 gives the results of crossing Blue Pod Butter with 

 pink-flowered black-seeded sorts. As already stated none of the 

 waxy-pink flowers appear among these crosses. White flowers 

 appear among the progeny of the crosses of Blue Pod Butter X 

 German Black Wax, but not in the reciprocal cross, also in the 

 cross of Currie and Blue Pod Butter. Light pink flowers ap- 

 pear rarely, and they may be extreme variants of pink floAvers 

 in which the color has been partially suppressed by environ- 

 mental conditions.
