Autotetraploid Breeding in Perennial Rye (Secale cereanum): Cytogenetic Challenges, Agronomic Potential, and Future Prospects
Perennial rye (Secale cereanum), an interspecific hybrid derived from cultivated rye (Secale cereale L.) and perennial wild rye (Secale strictum), has potential for the development of more sustainable perennial cereal systems. However, its breeding and agronomic utilization are constrained by low fertility and irregula...
