Abstract: A field experiment was carried out at Abu Ghraib Research Station, the Agricultural Research Department, Ministry of Agricultur, at seasons 2016-2017 to evaluate the response of cultivars wheat (Abu Ghraib 3 and Iba 99) to weed control by herbicide Pallas 45 OD. Randomized Complete Block Design (RCBD) was use in three replication. The results could be summarized as following Pallas with cultivar (Iba99) gave lowest number of weed at growth stage 30, 60 and 90 days after application by 9.6, 12.2 and 15.3 (plant. m-1) respectively while weedy treatment gave highest value by 98.0, 106.9 and 130.2 (plant. m-1) respectively, so Pallas reduced number of weeds at these stage by 90.2 %, 88.6 % and 88.2 % respectively according to weedy treatment, the treatment of Pallas with cultivar (Abu Ghraib 3) caused reduction of number of weeds by 91.0 %, 90.0 % and 84.0 % according to weedy treatment. Pallas treatment with cultivar (Abu Ghraib 3 and Iba 99) the same effected in dry weight of weeds, so it caused inhibition by 88.0 % and 88.4 % according the weedy treatment. The wheat positively respond and gave high value at yield and components for the treatment of Pallas with the cultivar Abu Ghraib 3 (number of spikes per unit area, number grains of spike, weight of 1000 grain, grain yield and biological yield) by 57 %, 29 %, 63 %, 48 % respectively according to weedy treatment, for the treatment of Pallas with the cultivar Iba 99 by 39 %, 21 %, 30 %, 62 %, 50 % respectively according to weedy treatment. This results may be attributed to the genetic variation of nature for wheat classes.
