Abstract

This study investigates the use of ethyl methanesulfonate (EMS) mutagenesis to enhance the genetic traits of walnut seeds. By varying EMS concentrations, treatment times, and temperatures, optimal mutagenesis conditions are identified to construct a diverse mutant library. Phenotypic and genotypic analyses reveal mutants with superior characteristics, such as enhanced disease resistance, improved growth vigor, and higher yield potential. These mutants contribute valuable genetic resources for walnut improvement programs. The findings offer an effective method to enhance walnut seed quality and yield, potentially increasing farmers' income and supporting sustainable agriculture. Additionally, the study highlights the potential of EMS mutagenesis as a practical tool for accelerating breeding programs and generating genetic diversity in walnut populations.
