Yield components and some morphological characters were studied in seven wheat varieties in order to find out the genetic association of different characters towards grain yield. The experiment was conducted in randomized block design (RBD) with four replications, at Adhiyamaan college of Agriculture Research, Athimugam, Tamil Nadu during 2016–17. Path analysis identified that grains spike−1 had the highest positive direct influence on grain yield followed by 1000 grain weight, days to maturity and tillers m−2. Grain weight spike−1, days to heading, spike length and plant height had negative direct influence on the grain plot−1.
