for Yield and Yield Components in Oromia, Ethiopia
Author(s): Berhanu Sime* and Shimelis Tesfaye
The study of GEI has assumed great importance in genotype testing programs because yield performance of a genotype is a result of the interaction between the genotype and environment. The study cried out with objectives to determine the effect of genotype, environment, and GEI on yield and yield components and to identify stable genotype. Twenty five bread wheat genotypes were evaluated by Alpha Lattice using three replications at six locations in Oromia, Ethiopia. Combined analysis of variance showed very highly significant differences (P<0.01) among environments and among genotypes. Genotype’s contribution to variation of some of the traits is equal or more than 30% except NGLS and GY. The contributions of environment to the total sum of squares of treatment is very high for GY and lower for NSLS, NGS, NGSL and TKW traits. Comparatively, contribution of G × E to the t.. View more»
