Title
Application of GGE biplot analysis to evaluate GxE interaction on Maize Hybrids
Authors
Abstract
The main difference in the stability of genotypes due to cross-interaction of genotype and environment, the
changes in their rankings in various environmental conditions and there are Various methods of stability
analysis and evaluate the effect of genotype × environment interaction .In this research 15 maize hybrids
were studied in form of randomized complete block design with 4 replicates across 6 environments including
3 agriculture research center (Karaj, Mashhad and Jiroft) in two years (1390-1391). for studying interaction
effect and determining stable hybrids, the GGE BIPLOT multivariate method was used .The results
showed that the first two principal components regression model explained 92% of the observed changes.
By using BIPLOT polygons, six Top genotypes and two mega environments were identified. Also based on,
both yield and stability BIPLOT, genotypes number 2 and 5 ,were identified as stable genotypes with
average function. Evaluation of genotypes relative performance revealed that genotype No. 5 in Karaj and
genotypes 14 and 2 in Mashhad and Jiroft , have the highest performance.
