Secale sylvestre

Secale sylvestre is a wild relative of rye (S. cereale).

Breeding
Secale sylvestre is useful for wheat breeding. This includes disease resistance breeding.

Genomics
Secale sylvestre is the source of PmSESY, a disease resistance gene for wheat powdery mildew. He et al., 2021 use genetic mapping to locate PmSESY on the 1RL chromosome.
