Spectrum and rate of winter wheat mutations caused by nitrosoalkylureas
Journal Title: «Таврійський науковий вісник» - Year 2017, Vol 98, Issue
Abstract
Winter wheat varieties were treated with chemical mutagens at the following concentrations: NEU (nitrosoethilurea) – 0.01 %, 0.025 %, NMU (nitrosomethilurea) – 0.0125 %, 0.025 %. The spectrum and rate of mutation were investigated. We isolated mutant lines with changed traits, investigated their heredity. Overall, thirty-five mutation traits were identified. Three new high grain productivity lines have been developed. We recommend using low concentrations of NEU and NMU in mutation breeding for getting economically valuable mutations.
