Article 6
1. Each Member State shall establish a list of the varieties of fodder plant officially accepted for certification in its territory ; the list shall give the main morphological or physiological characters by which varieties of plants directly derived from seed of the category "certified seed" can be distinguished one from another, and the officially established maximum number of generations accepted for certification produced from the basic seed of each variety. In the case of local varieties the list shall indicate the region of origin. 2. In the case of hybrids and synthetic varieties, the authorities responsible for acceptance and certification shall be informed of the genealogical components. The Member States shall ensure that the results of the examination and the description of the genealogical components are, if the breeder so requests, treated as confidential. 3. A variety shall be accepted for certification only if it has been established by official or officially controlled examinations, particularly growing trials, that the variety is sufficiently uniform and stable. 4. The varieties accepted shall be officially checked at regular intervals. If any of the conditions for acceptance for certification is no longer satisfied, acceptance shall be revoked and the variety deleted from the list. 5. These lists and any alterations made to them shall be sent forthwith to the Commission, which shall communicate them to the other Member States.
