Breeding for seed yield is a lever that is not much activated. Indeed, the evaluation of seed yield components requires specific experimental conditions that comes in addition to the ones used for the evaluation of forage-related traits. In addition, the genetic resistance to pests that are particularly damaging the plants at reproductive stages has not been much studied. Current knowledge is quickly reviewed and suggestions to implement molecular breeding are proposed. Selection for both forage and seed traits could be managed in cost-effective breeding schemes.
