Autonomy of Cytoplasmic Male Sterility in Grafted Scions of Tobacco.

Negative results were obtained in experiments designed to detect graft transmission to progeny of cytoplasmic male sterility in tobacco, contrary to positive results reported by Frankel in petunia. Attempts to show graft transmission of male fertility also failed. Evidently transmission of cytoplasmic male sterility through a graft union with a fertile individual is not an easily repeatable or else is not a general phenomenon in plants.
