[Obtaining mutations with cytoplasmic male sterility (CMS) in Dactylis glomerata L. under the influence of chemical mutagens].
When treating seeds of orchard grass with definite concentrations of nitrosoethylurea (NEU), dimethyl sulphate (DMS) and ethylene imine (EI) in M1 and M2 the plants with CMS as well as sterility fixators to them are obtained. Proportionality of mutagenic action and stimulation effect of these substances are found. The greatest amount of sterility fixators is found in M1 among plants the seeds of which were treated with NEU and EI; in M2 the fixators are found among plants obtained after treating seeds with DMS. Sterility fixators were found among plants of the VIK-61 and Asta and VIK-61XAsta hybrid population.
