Plants genotipically Sml/sml r/r, segregating or not for Ac, were selfed and mated to r-scm:3 Sml no Ac (colorless seed) females, a stock monitoring the presence of active Ac by inducing spotted kernels. The selfed progeny was germinated and scored for the presence of dgr and sml seedlings. wt, Wild type.

a

 Colorless refers to ears yielding only colorless seeds, whereas spotted refers to ears with spotted and colorless seeds in a 1:1 ratio. 

b
