Research

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?
