Estimation of Genetic Variation for Agro-Economic Traits in Wheat (Triticum aestivum L.)

Muhammad Tariq Mahmood, Shah Jehan Khan, Imtiaz Ali, Sabir Hussain, Syed Awais Sajid Shah, Muhammad Attiq Sadiq, Muhammad Ashfaq, Farman Ali


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.
