Secale is a genus of the grass tribe Triticeae, which is related to barley (Hordeum) and wheat (Triticum).

The best-known species of the genus is the cultivated rye, S. cereale, which is grown as a grain and forage crop.

Commonly recognized species of the genus are the annuals, S. cereale, S. vavilovii Grouch, and S. sylvestre and perennial S. strictum (syn.

strictum evolved in succession from a common ancestor of Secale after geographic separation and genetic differentiation.

Many forms of perennial rye are found in Turkey including Secale montatum Guss var.

These perennial species usually have large stature, high frost resistance, strong tillering ability, and tolerance to poor soils and drought.

Beneficial characteristics of the crop include early growth in spring, competing well with weeds, and producing significant regrowth for silage or pasture.
