Heterosis and its possible exploitation in swedes (Brassica napus L. ssp. rapifera)

  • Published:
Euphytica Aims and scope Submit manuscript

Summary

Considerable heterosis has been demonstrated in inter-cultivar swede hybrids. Increases in dry matter yield of between 5.9 and 25.6% over the superior parent were obtained. Difficulties and possibilities with regard to the commercial exploitation of this phenomenon in swedes are discussed.
