The present experiment on spring wheat (Triticum aestivum L.) was carried out with 15 parents and 44 F1's developed from line x tester mating design to find out the genetic association among various important economic characters for the purpose of genetic enhancement in the grain yield in wheat. The parental lines (11 lines and 4 testers) were grown during rabi, 2012-2013 and 44 cross combinations among lines and testers were made and the seeds of parental lines and 44 crosses were procured. The experiment was conducted at Crop Research Center (Chirodi Block) of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut (U.P.) under timely sown conditions during rabi, 2013-14. Estimation of correlation coefficient at phenotypic level, grain yield per plant exhibited significant and positive correlation with harvest index, biological yield per plant, flag leaf area, spikelets per spike and days to maturity indicating selection can be done on the basis of these traits for the improvement of grain yield in wheat strains as these are major contributors to the grain yield. Genotypic and phenotypic path coefficient revealed that harvest index and biological yield per plant had high (0.30 to 1.00) direct effect on grain yield. Biological yield per plant and harvest index had high positive effect on grain yield per plant. Therefore, direct selection for these two traits would be effective for further yield improvement in wheat genotypes.
