The experimental material was sown in the experimental area of Department of Plant Breeding and Genetics, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during 2004-2005, comprising of 10 wheat genotypes viz., Chakwal-86, Iqbal-2000, Uqab-2000, GA-2002, 00FJ03, IC-001, IC-002, NR-234, 3C061 and 3C062 for determination of interrelationships among yield and yield related characters. Analysis of variance showed highly significant differences among the genotypes for all the traits. The correlation coefficient indicated that spike length, number of spikes per plant, number of spikelets per spike, number of grains per spike, number of tillers per m2, 1000-grain weight were significantly and positively correlated with grain yield per plant, while days to heading, days to maturity and plant height showed non significant correlation with grain yield per plant.
