This study was conducted to estimate heterosis for the yield and yield contributing traits of 3 different cross combinations involving 6 diverse genotypes obtained from CIMMYT at the experimental field of Hazara University, Mansehra in 2016-2017 growing season. The experiment was designed in a Randomized Complete Block Design (RCBD). All three cross combinations showed desirable negative better parent heterosis for days to 50%heading and days to maturity. Highest positive significant mid parent hetersosis in plant height is exhibited by cross C (7.17*). Biological yield is one of the important yield attributing trait, all 3 crosses showed nonsignificant but positive values in MPH for this trait (7.02, 8.89 and 1.85 respectively). Crosses A and B resulted in positive significant heterosis over mid parent for trait of plant yield and cross C showed positive but nonsignificant MPH (13.45*, 18.07* and 6.93). Heterotic hybrids with maximum number of studied desirable yield contributing traits (3) identified only one cross B. The present study suggests ample scope for exploitation of heterosis for commercial production of hybrid wheat by involving early maturity trait for getting further breakthrough in wheat yields.
