Bio Brief

Molecular mapping and categorization of wheat genes expressing resistance to the greenbug, Schizaphis graminum (Rondani)


Ph.D. Entomology, Kansas State University, 2005


My research is comprised of two interrelated projects. The first project focuses on molecular mapping of greenbug resistance genes in newly identified wheat germplasms. In this project, I have mapped six greenbug resistance genes Gbx, Gbz, Gba, Gbb, Gbc and Gbd in wheat accessions KS89WGRC4, KSU97-85-3, as well as synthetic wheat lines TA4152L94, TA4152L24, TA4063L1 and TA4064L2, respectively. My second project focuses on resistance categorization of wheat lines KS89WGRC4, KSU97-85-3, Largo and TAM110 to biotype K greenbug feeding. I am trying to answer the following questions in this study:

  • Do categories of resistance express differently in response to different biotypes of greenbug feeding?
  • How does genetic background of wheat affect resistance categories?
