Abstract

Sunn pest, Eurygaster integriceps Puton, is the most damaging insect pest of wheat in West and Central Asia and East Europe. Host plant resistance has been investigated as one component of a total integrated pest management program for the control of this pest. In Syria, field screening of artificially infested wheat accessions from the International Center for Agricultural Research in the Dry Areas (ICARDA) gene bank, selected using the Focused Identification of Germplasm Strategy (FIGS), identified one durum wheat and eight bread wheat accessions with good levels of resistance at the vegetative stage to overwintered Sunn pest adults. ICARDA is using these sources of resistance in wheat breeding programs to develop cultivars resistant to overwintered Sunn pest adults, which damage wheat at the vegetative stage (shoots and leaves). This study also demonstrated that the FIGS approach was effective in mining genetic resource collections for useful traits.
