Abstract

A total of twenty five bread wheat (Triticum aestivum L.) genotypes were evaluated for trait association and path coefficient analysis among yield and yield contributing traits at Gurage zone of two different environments. The genotypes were grown in triplicate randomized complete block design. Data were collected on 13 agronomic characters. It was found results that grain yield showed positive and significant correlations with above ground biomass, tillers per plant, kernel per spike, spikelet per spike and plant height at Fereziye and negatively correlated with tiller per plant (rg= -0.535) and plant height (rg= -0.284) at Kotergedra. Selection on the basis of positive association of grain yield with its contributing traits may be helpful to improve grain yield of wheat. Path coefficient analysis revealed that above ground biomass and tillers per plant exerted high and favorable direct effects on grain yield at Fereziye. Both genotypic and phenotypic correlation and path coefficient analysis revealed that grain filling period exerted high and favorable direct effect on grain yield at Kotergedra which indicated that selection on such traits may be useful to improve the grain yield. It was moreover suggested that the evaluation of wheat genotypes for grain yield under multi-zonal locations should be carried out to exploit more yield potential.
