ABSTRACT
Mitochondrial genome variability was studied in a gynodioecious population of Rosmarinus officinalis L. Analysis of mitochondrial DNA organization using Southern hybridization with probes for mitochondrial genes coxll, cob. and atp A revealed a high level of mitochondrial polymorphism; 11 mitotypes were detected in a total of 27 individuals studied. One mitotype was particularly common among male fertile individuals. The remaining mitotypes were found in only one or two individuals, generally male sterile. Polymorphism was thus greater in male sterile than in male fertile individuals. The data presented here suggest that male sterility in Rosmarinus is associated with the appearance of mitochondrial genome variants which differ from the standard pattern for male fertile plants.
