Embrapa selects producers for agronomic validation and licensing of forage sorghum BRS 661

The Embrapa (Brazilian Agricultural Research Corporation) announces that it will select producers interested in evaluating the agronomic performance, multiplication and commercialization of seeds of the forage sorghum cultivar BRS 661. Seed producers must be registered in the Renasem (National Registry of Seeds and Seedlings) . The BRS 661 cultivar, developed by the Embrapa Milho e Sorgo breeding program, according to analyst Reginaldo Resende Coelho, is an open pollinated variety that stood out in the trials, bringing together important suggestive attributes for its recommendation for silage.

Interested producers should send an email to the address cnpms.chtt@embrapa.br with the subject “Selection Notice No. 04/2023” containing the information detailed in the notice. E-mails must be sent from 8am on 27/01/2023 until 17pm on 10/02/2023.
