Abstract
Breeding maize hybrids is a slow and expensive process. Maize hybrids perform differently under different environmental conditions and agricultural management practices, making hybrid selection one of the most important management decisions for maize growers. Choosing the right maize hybrid with high yield potential for the location can improve profitability, grain yield and quality at harvest.
The experiment was carried out at the University of Debrecen Institutes for Agricultural Research and Educational Farm (AKIT), Debrecen Agricultural and Landscape Research Institute (DTTI), Látókép Crop Production Experimental Station to evaluate the yield parameters of three maize genotypes with different maturity (FAO 350, FAO 400 and FAO 460). Our studies evaluated the yield, quantitative and qualitative characteristics of maize hybrids and the yield determinants of yield.
In terms of yield, in the "potential" field experiments, the excellent FAO 400 maturity maize hybrid KWS FORTURIO achieved a peak yield with a record value of 20.05 t/ha, which exceeded the yield of the other genotypes tested by 12.29–14.83%, a significant difference.
Significant differences in starch content were measured among the tested hybrids, with the highest result obtained by the FAO 350 maturity KWS OLTENIO hybrid with 63.78%.
Based on our analyses, we found that some quantitative and qualitative yield traits are genotype specific, which results support the importance of selecting the most suitable maturity genotype for the production objective.
