Detection Of New Strains Of Weeds Associated With Wheat For The First Time In Iraq

Abstract

The expected losses in wheat crop due to the associated weeds can be the real threat to the production of this crop and the wellbeing of growers as more than 20 genera of weeds are spreading in all regions that growing by wheat in Iraq. However, the most widespread and harmful genera are those belonging to Poaceae, Brassicaceae and Fabaceae families. The geographical distributions, morphological identification confirmed by molecular identification were conducted to detect weed species associated with wheat crop in Babylon province. Results indicated that the average of density of weeds spread was 20.38% in 632 hectare cultivated with wheat. Eight strains belong to different families of weed were recorded for the first time and registered in GenBank (NCBI) under the accession numbers (OM069771 to OM069778). The phylogenetic tree and development of the genetic patterns of registered strains with forty compatible species were divided into several groups that showed different inherent in kinship and closely interdependence despite the difference in locations of groups.
