maize mutant phenotypes

Ds-Cbreakers, C1-I; (C1-I Ds-9S1) & (b1-dm Ds-2S4) with Ac A double-pollinated ear of an Ac/-, b1-dm Ds-2S4/b plant. The top half silks were pollinated by bb rr pollen, and show a 1:1 segregation for purple vs colorless, indicating that the 2-dose (b-dm/b-dm/b) kernels are full-colored and not pale. The bottom half, pollinated by homozygous C1-I Ds-9S1 no Ac, has two classes of kernels: 1) those that are colorless have no dots because they lack Ac; 2) those with a pale background composed of many tiny pale two- to four-celled dots and fewer darker and larger dots and sectors and a scattering of intense full-colored dots. These probably are the b-dm/b-dm/b, Ac/-/-, C/C/C-I Ds kernels.
