Tolerance to Imazamox Herbicide Found after Screening of Advanced Generation Lentil Mutant Genotypes

In Turkey, one of the essential grain legumes is lentil. It usually perceived as a weak competitor with weeds. The research objective was to determine tolerance selected 145 mutagenized lentil genotypes at M5 generation imazamox herbicide including 139 derived from Ethyl Methane Sulfonate (EMS) seeds cultivar Firat-87 and 6 control cultivars were screened for tolerance. Experiments carried out in greenhouse field. Herbicide applied 150% recommended dose (100 ml/ha, or 40 g a.i/ha) when plants between 5 - node stage. response evaluated by measuring plant height sign growth also visual scoring foliar damage 1 scale 45 60 days after spraying field experiment 30 experiment. categorized based on their reactions herbicides highly tolerant, moderately sensitive, sensitive. results showed significant differences among herbicide. At spray, most some recoveries both experiments. Five (IMI-124, IMI-128, IMI-130, IMI-138, IMI-139), displayed high tolerant can be exploited future breeding programs improving varieties.
