Abstract :Avena fatua L. (wild oat) is a major weed species that causes yield losses in wheat fields and threatens agricultural production. In order to develop effective management strategies, it is essential to understand the morphological diversity of this species. Morphological differences between populations reflect the plant\\\'s ability to adapt to environmental conditions and its competitiveness, which can help in the selection of appropriate control methods. This study was conducted to reveal the morphological diversity of A. fatua populations, which are common and constitute an important weed problem in wheat cultivation areas of Iğdır province and its surroundings. For all parameters except stem diameter, statistically significant differences were found at the 1% level (p<0.01). The plant height ranged from 163.00 cm to 83.25 cm, leaf length from 32.50 cm to 15.75 cm, spike length from 43.75 cm to 24.00 cm, flower count from 57.50 to 24.00, fresh weight from 26.50 g to 15.75 g, and dry weight from 13.50 g to 2.75 g. Particularly, populations such as IĞR22 and IĞR30 stood out with high plant height and flower count. Furthermore, through multivariate analysis, similarities and differences between the populations were visually assessed, and it was observed that populations such as IĞR8, IĞR30, IĞR7, IĞR22, and IĞR18 were distinctly separated from others. The study demonstrates that there is significant morphological diversity among A. fatua populations. This diversity allows it to have the capacity to adapt to different environmental conditions and to spread more effectively in agricultural areas. In this context, a more detailed study of the morphological characteristics of Avena fatua will contribute to the development of effective weed control strategies.
