C-Im857101 - an unstable C-I allele responsive to En

This is an En-responding C-I-m allele arising from a population as in Cross 1 (preceding report). This conclusion is based on results from crosses of C2/c2-m2, C wx-m8 x C2, C-Im857101 Wx/C-Im857101 wx. Colorless (or palish) and sectored (colored to colorless) were isolated. Of the 28 wx sectored kernels tested, all showed wx to Wx. This indicates that the C to C-I sectoring is controlled by En.
