Four maize hybrids bred at the Cereal Research Non-Profit Company in Szeged were registered at the National Institute for Agricultural Quality Control (OMMI) during the period 2001-2004. The registration of five Szeged hybrids is expected on the territory of the European Union in 2005-2006. The hybrids are accompanied by specific production technological guides for commercial production based on the results of agronomy trials, so that the genetic potential of the hybrids can be utilised in practical farming to the highest possible extent. The specific agronomic traits of hybrids with different vegetation periods and genotypes are investigated. If a maize hybrid is to be recommended to farmers, it is necessary to know not only its yield potential, but also its yield stability. For this reason, investigations are also made on the effect of soil and climate on the grain yield potential of each hybrid individually.

The Duo-System technology, which is basically a combination of the Focus Ultra herbicide and cycloxydim-tolerant maize hybrids, is spreading as a tool for weed control in maize crops. The Cereal Research Non-Profit Co. Ltd. commenced the breeding of cycloxydim-tolerant maize (CTM) hybrids based on know-how from BASF. CTM hybrids were created by crossing the CTM inbred lines developed in the initial phase of the programme. The herbicide tolerance of the hybrids was tested in dose rate trials with Focus Ultra in 2008 and 2009. The agronomic value of the novel CTM hybrids was tested in performance trials in 2009. CTM hybrids with high yield potential have been selected as a result of the breeding programme.
