Improvement of genotypes can be achieved by using of the agronomic traits that may respond to the environmental stresses. Complexity of grain yield, and so the high cost of evaluation of germplasm in different environments cause the agronomic traits and their relationships with grain yield become important. In order to study the relative importance and direct and indirect effects of agronomic traits (as selection criteria) on grain yield, this research was conducted at Gachsaran Agricultural Research Station in 1997/98 cropping season. In the experiment, 120 barley genotypes were evalutad in an augmented design. Using stepwise regression and path analysis indicated that grain filling period and plant height showed high relationship with grain yield. Therefore, the two traits are suggested as effective criteria in selection of barley genotypes in heat and drought stress conditions.
