Analysis of the existing methods for earliness group determination of maize varieties and hybrids according to the FAO indices was conducted. Influence of the abiotic factors on earliness of 16 standard maize hybrids in all agroclimatic zones of Ukraine at nine State Canters for Plant Variety Examination and State Variety Testing Stations during 1999-2006 was analyzed. On the base of the research results, a new method of earliness group determination for varieties (hybrids) of maize without comparison with the standard hybrids has been developed.
