Breeders may consider the use of male sterility when developing hybrid varieties or when making complex bulk crosses.

Male sterile plants may have a reduced seed-set and consequently a reduced fitness as compared to male fertile plants. Selection with regard to sex expression is therefore an issue of practical relevance.
