Abstract

To determine the most precise possible manner of the cause and effect relations between yield and yield components, a simple CORRELATION method in the path of coefficient analysis was used in 10 line of BARLEY. During the growth season and after yield harvesting, 14 character Istic data were recorded. Results of analysis of variance showed significant differences among lines in terms of traits under 5% and 1% probability of levels, which indicated the existence of genetic variation. Yield of lines showed the significant difference, just 1% and the first line had the most yields. Using stepwise regression was formed the best suitable model at yield. Using PATH ANALYSIS, CORRELATION between characters, which remainded into the model was broken to direct and indirect effects. The highest positive CORRELATION (0.75) was obtained between harvest index and GRAIN YIELD which resulted in high direct effect of harvest index on GRAIN YIELD (0.9561). Also biological yield direct effect was obtained high and positive on GRAIN YIELD and had positive CORRELATION with GRAIN YIELD. Grain number per spike was also found to be positively insignificant direct effect on yield, but indirect effects through biological yield and harvest index were fairly high.
