Overview

Randomized trial evaluates sesame genotypes' resistance to bacterial blight in sesame crops, indicating potential resistance sources.

Key Points

  • The aim is to evaluate sesame genotypes for resistance to bacterial blight disease.
  • 77 sesame genotypes assessed under field conditions
  • Inoculum prepared to a size of approximately 10^7 CFU/ml
  • Disease severity assessed on 8 tagged plants per genotype to estimate leaf area affected.
  • No genotypes were resistant, 54 moderately susceptible, and 8 sensitive in 2019; 23 moderately resistant, 57 moderately susceptible, and 7 susceptible in 2021.
  • Significant variation observed in disease severity, growth, and yield among genotypes.
  • Some genotypes identified as potential sources of resistance and better yield performance.
