Five wheat lines viz. DN-89, DN-88, DN-84, DN-76 and DN-69 were evaluated to test the genetic variation for agronomic traits to identify the lines with best genetic constitution and capable of best results under agro-climatic conditions of Dera Ismail Khan. The experiment was carried out using RCBD design with three replications at Department of Plant Breeding & Genetics, Faculty of Agriculture, Gomal University Dera Ismail Khan, Pakistan. Results showed that  the agronomic characters i.e. number of tillers plant-1, spike length (cm), 1000-grain weight and yield kg ha-1 are major yield contributory parameters. The line DN-76 produced significantly highest grain yield (5842 kg ha-1. The other traits viz number of tillers plant-1, spike length (cm), 1000-grain weight and yield kg ha-1 the same line was found highest and significant than the other lines. Therefore, DN-76 is best suited for general cultivation in agro-climatic conditions of Dera Ismail Khan Zone.
