Abstract: The better way of exploiting genetic association with several traits having high heritability is to construct a selection index that combines information on all the characters which are having decisive role in influencing the yield. Therefore, an experiment consisting thirty wheat genotypes was grown in a randomized block design with three replications during Rabi 2007-08 to determine mutual relationship between various yield components in bread wheat. The mean performance of individual genotypes was employed for analysis of variance to test the significance for each character. The higher genotypic and phenotypic coefficients of variation were exhibited by harvest index, biological yield per plant, number of productive tillers per plant, test weight and grain yield per plant. The role of additive gene action was observed in the expression of the character like plant height, grain yield per plant, biological yield, harvest index and test weight. The correlation coefficient between grain yield per plant and other quantitative attributing to yield showed that grain yield was positively associated with plant height, spike length, number of grains per spike and test weight and biological yield. Path coefficient at genotypic level revealed biological yield had the highest direct positive effect on seed yield per plant followed by harvest index, days to maturity, test weight, spike length and number of productive tillers per plant, indicating these are the main contributors to yield.
