Overview

Analysis reveals hybrid progeny inherit significant insect resistance, indicating varying growth patterns due to ploidy effects.

Key Points

  • Hybrid progeny displayed an average larval mortality rate of 97.03%, confirming high insect resistance from BtCry1Ac.
  • Ploidy analysis indicated all hybrids were aneuploid, showing lower survival rates compared to the maternal parent.
  • Embryo rescue techniques were employed for hybrid production, facilitating tissue culture and genetic analysis outcomes.
  • Transgene expression levels varied, influenced by copy number, insertion sites, and the ploidy status of the progeny.
