c-m888104
- a mutable allele under 2-element control
--Peter A. Peterson
In a segregating population arising from
the self of c-m/c sh wx, colorless shrunken and colorless
round were selected from kernels segregating for variegated round, colorless
round and colorless shrunken. In the cross of colorless round x numbered
colorless shrunken, the following segregating progeny was observed.
Colored

Spotted

Colorless

This would indicate that the colorless
round is a responsive allele responding to a separable element carried
in the colorless shrunken kernels. Since this mutable arose in a Cy-containing
plot, the initial tests were for a Cy relation. These tests exclude
Cy as the functional element triggering mutability.
