Abstract

This experiment was performed to evaluate the correlation between grain yield and other characteristics of 20 cultivars and advanced breeding lines of barley in the Research Station, Agricultural collage, Shiraz University, Shiraz, Iran. The experimental design was a randomized complete block with four replications. Biological and grain yields and yield component were measured. Genotypic and phenotypic variation, mean comparison, correlation coefficient, regression and hordeum-vulgarePath analysis were used for analysis of data. The Path analysis showed that the effects of spikes per square meter, kernel weight on grain yield were significantly different (p . Also the results showed spikes per square meter had a negative correlation with kernels per spike and kernel weight. Regression analysis confirmed that kernel per spike is the most important yield component and increasing it can be improved the grain yield.
