Variety description

10 August 2026

The variety is a historical selection mentioned in agricultural registers and publications from the 1970–2000s period. The primary purpose of this ryegrass was the establishment of dairy pastures for livestock grazing.

In scientific literature, the variety is mentioned in the context of research on plant resistance to the rust Puccinia coronata. However, detailed agronomic characteristics, such as plant height, precise maturity group, or lodging resistance, are not presented in open sources as a unified description.

The name Astor is also found in international documents in relation to Italian ryegrass and oats, which complicates the unambiguous identification of the agronomic traits of the specific variety. In modern production catalogs, the variety is practically absent due to the emergence of more current breeding achievements.
