Tests of Hooker-Russell exotic sources of cytoplasm converted to inbred H632 for a cytoplasmic fertility restorer

Tests of Hooker-Russell exotic sources of cytoplasm converted to inbred H632 for a cytoplasmic fertility restorer

The six lines not previously tested (MNL 56) do not carry a cytoplasmic restorer of genetic male-sterile #1. This completes the test of 40 of those lines. One line (PI 174990 x B14¹⁶ x A632¹⁴) has not been tested. I have been unable to establish the stock.

If a cytoplasmic restorer is specific for a particular male-sterile gene, it will be necessary to test the other male-sterile genes.
