Abstract excerpt
BACKGROUND: As a tetraploid plant, alfalfa (Medicago sativa L.) exhibits complex genetic mechanisms that pose significant challenges for the integration and stabilization of superior traits. In this study, space mutagenesis–a highly efficient and stochastic gene mutation induction technique–was employed to treat ‘Deqin’ alfalfa seeds. Through ground-based selection, a mutant line with enlarged leaves was...
