AMMI and GGE Biplot Analyses for Mega- Environment Identification and Selection of Some High-Yielding Oat (Avena sativa L. ) Genotypes for Multiple Environments. Nairobi, Kenya: International Livestock Research Institute (ILRI).

To lessen the impact of Genotype x Environment interaction and to increase the precision and reliability of genotype selection, the yield and stability of performance should be taken into account simultaneously. Two methodologies of analysis (AMMI and GGE) approved selecting ILRI_5527A/G6 for a further breeding program or for high-production growers in Adiyo, Doyogena, Chencha and Hulla locations of Central Ethiopia.
