Allelopathic potential of wheat plant and genotypic variation among cultivars has been observed in
several studies. In order to recognize and screen allelopathic potential of wheat genotypes against Amaranthus
retroflexus, Hordeum spontaneum and Avena fatua, a glasshouse experiment was conducted, using 68 wheat
genotypes. Root and shoot water extracts of wheat genotypes were prepared from fourth leaf stage wheat plants.
Weeds root length was measured after germination in Petri dishes exposed to wheat extracts. The results
showed considerable variation in inhibitory potential of wheat genotypes. Shoot extracts had higher allelopthic
effects than root extract. The highest inhibitory effects were observed in the cultivars Rasool, Mahdavi, Navid,
Karaj1, Adl1, Gaspard, Gascogen, Bam, Arvand, Baiat and Azadi, but high variation in weed responses were
observed. In conclusion, some wheat genotypes had more allelopathic potential so they could be built into weed
management programs.
Key words: Allelopathy, genetic variation, water extract, weed management, , ,
