Overview

Analysis identifies SSR markers associated with Cry toxin resistance in Pectinophora gossypiella, suggesting improved management strategies.

Key Points

  • The aim is to identify and validate SSR markers linked to resistance against Cry toxins in Indian pink bollworm populations.
  • Analyzed 59 Pectinophora gossypiella populations across India.
  • Employed bulk segregant analysis to identify SSR markers.
  • Conducted larval bioassays to confirm resistance levels.
  • The Nagpur population showed the highest resistance levels to Cry toxins.
  • Identified three SSR markers associated with Cry1Ac resistance.
  • Marker gF47/gR47 linked to resistance against both Cry1Ac and Cry2Ab.
