Variety description

10 August 2026

The Kamex variety is a type of butterhead lettuce. It is mentioned in European vegetable variety catalogs and materials related to Czech breeding as genetic material from specialized banks.

In agronomic practice, the variety is considered to have been phased out of use. In the specialized catalogs of breeding companies, the characteristics of Kamex are provided primarily in the context of comparison with its successor, the Kamenex variety, which performs similar functions in modern production.
