In order to study genetic variability and correlation among various wheat genotypes, an experiment was conducted comprising twenty five F5 populations during 2008-09 at the Malakandher Research Farm Peshawar. Data were recorded on grains spike-1, grain weight spike-1, 1000 grain weight , biological yield, harvest index and yield ha-1. Analysis of variance revealed highly significant differences for grains spike-1, grain weight spike-1, biological yield and grain yield ha-1 while non significant differences were observed for 1000 grain weight and harvest index among all the populations. Phenotypic correlation coefficient of grain yield with grains spike-1 and grain weight spike-1 were significantly positive. Based on these results we concluded that the populations of Tak x Inq and G-98 x Tat could yield potential segregates.
