A pollen-restorer sugarbeet inbred, developed by four generations of selection of highly fertile plants from a CMS X table beet cross, was studied to determine if a change from sterile to fertile cytoplasm had occurred. Data showed that the fertility expressed by the restorer inbred was the result of genetic factors and not cytoplasmic reversion. Linkage tests with the Rf gene showed independence of the YRB group, m and vi4. A yellow-loaf mutant was inherited as a simple recessive factor. A partial pollen-restorer character, found in the yellow-leaf material, was inherited as a single dominant gene. The restorer factor was independent of yl and m, while the yl gene showed independence of m and B.
