Overview

Randomized trial evaluates the effects of EMS treatment on barley performance and chromosomal stability, indicating dose-specific implications.

Key Points

  • This study aims to evaluate how different concentrations of EMS impact agronomic traits and chromosomal stability in barley.
  • Evaluated four barley advanced breeding lines under greenhouse conditions.
  • Seeds treated with 0.1%, 0.2%, and 0.3% EMS concentrations, plus an untreated control.
  • Assessed germination, seedling vigor, plant height, tiller number, and chromosomal traits.
  • Germination and seedling vigor declined by 20–50% with increasing EMS concentration.
  • Moderate EMS treatment (0.2%) increased grain number per spike while maintaining stable grain weight.
  • Chromosomal aberrations increased significantly at 0.3% EMS, leading to enhanced genotoxic stress.
