The main reason that makes breeding for the main yield components difficult is that they are in negative correlation with each other. Numerous researchers have studied relations between yield and different yield components in order to find dependable selection criteria. The goal of this paper is to estimate the variability and correlations between yield components. The experiment was conducted on twelve durum wheat genotypes. Plant height was in both years positively correlated with number of spikelets per spike and negatively correlated with spike length. grain weight per spike. number of grains per spike and harvest index. Spike length was positively correlated with grain weight per spike and number of grains per spike. in both years and with harvest index only in the first year. while it was negatively correlated with number of spikelets per spike in the first year. Number of spikelets was in negative correlations with grain weight per spike and number of grains per spike in the first year and with harvest index in both years of investigations. Grain weight per spike was positively correlated with number of grain per spike and harvest index in both years. Number of grains per spike was in positive correlation with harvest index in both years of investigations
