Summary
Data are presented which indicate that a cytoplasmic/genetic type male sterility has been induced into backcross progeny derived from intergeneric hybridization between Festuca pratensis (female parent) and Lolium perenne. Large numbers of male sterile genotypes have been obtained in all the backcross generations examined. The frequency and purity of maintainer genotypes is low and requires further breeding and selection. Analysis of data suggest that at least two loci are involved in fertility restoration. Conclusions regarding the genetic model are tentative and require further analyses.
