Abstract

The Oltenia area is often affected by drought and heat that strongly influence plant development and yield. This paper aims at evaluation the genotype x environment interaction of yield and quality components of maize hybrids under different climatic conditions. The trials have been located on the experimental field at Agricultural Research and Development Station (SCDA) Simnic, during three years (2012, 2013 and 2015). As biological material, there have been used five Romanian maize hybrids: F376, Milcov, Iezer, F475M and Crisana. The results have shown that the genotype x year interaction influenced the yield and protein content, but not the oil content. The average yield for all examined hybrids was 2743 kg/ha, the average protein content was 14.70% and the average oil content was 5.22%. The yield was negatively statistically significant, correlated with protein content and with air temperature. As average values for the research period, the Iezer hybrid was highlighted by high yield and high contents of protein and oil, therefore, this Romanian hybrid is recommended for use in the future breeding programs.
