Determination of Morphological and Biological Diversity of Acetolactate Synthase Inhibitor Herbicides Resistant and Susceptible Wild Bishop (Bifora radians M. Bieb.) Populations

Emine Kaya Altop, Hüsrev Mennan


Bifora radians M. Bieb. is an annual weed that is native to Asia and found throughout the world. The broad ecological tolerance and competitive ability of B. radians makes it most important weed species in wheat growing areas. Variation studies of plants are becoming increasingly common because reliable information are necessary to know populations dynamics, occurrence of herbicides resistance and demographic data. B. radians collected from 51 different locations that 29 resistant and 22 susceptible populations to Acetolactatae synthase inhibitör herbicides were compared with respect to morphological and biological differences. The result showed that high morphological variability was found among resistant and susceptible B. radians biotypes and varied with similar geographic locations. Biological and morphological variability among B. radians populations would be influenced by agricultural practices, crop characteristics, geographic location and herbicide pressure.
