Application of AMMI model in zoning of FAO 400-500 maize hybrids

Identification of high yielding and stable genotypes is one the main goals in all breeding programmes. Estimation hybrids often aggravated due to presence genotype x environment (GE) interaction. One ways eliminate negative effect this interaction application reliable statistical models such as AMMI model, which singles out that have positive reaction improvement production environments. This research aimed establish specific maize interactions different environments two years by analysis. Twelve KWS belonging FAO 400-500, were examined over eight locations Vojvodina. The highest yield both had hybrid KWS2 (12.764 kg ha-1). Based on AMMI1 KWS9 showed stability adaptability at locations. According AMMI2, KWS1, KWS3 KWS12, adaptability, while KWS2, KWS6, KWS8, KWS10 a satisfactory level it necessary pay attention they order be recommended regions. Nevertheless, based Temerin, Kikinda Zrenjanin, similar response, points number trial could reduced. Obtained results would contribute more precise decision recommendation for certain region, but also defining further aims breeding.
