In recent years, the use of allelopathy in weed management has received great attention. In this study, the effect of allelopathy of a double haploid population of barley on the growth characteristics of wild rye and hedge mustard was studied in the Laboratory of Agriculture and Plant Breeding, Faculty of Agriculture, Zanjan University. Some germination traits (root and shoot length, fresh and dry weight of seedlings) and their heritability were measured in barley, rye and hedge mustard. The results showed that the double haploid lines, rye and hedge mustard are significantly different in terms of all four traits of fresh weight, dry weight, root length and stem length. Lines 25 and 34 showed the lowest allelopathy and lines 17 showed the highest allelopathy on rye. Lines 39, 48, 55, 65, 66, 68, 70, 75, 76, 77 and 82 of barley were also affected by rye allelopathy. Lines 73 and 17 had the highest rate of allelopathy on hedge mustard plant, as well. Except for the dry weight of barley control, the length of roots and stems of hedge mustard, which had low private heritability, showed moderate other heritability traits.
