On the use of genetic male sterility in screening for cytoplasmic-genetic sterility in barley

Abstract

A method is outlined for using genetic male sterility to screen for cytoplasmic-genetic sterility in barley. Since the method utilizes genetic male sterile plants as females, a very large number of crosses can be made. The critical cytoplasmic-genetic interaction will occur in the F₁ generation, further minimizing time and effort required in the screening process.

The method was put to test with materials from a breeding program. The desired cytoplasmic-genetic interaction was not observed. Since only ten male stocks were tested, it is suggested that further studies with stocks of more diverse origin might prove successful. {fx350-1}
