Abstract
Molecular mapping of genes for crop resistance to the greenbug, Schizaphis graminum Rondani, will facilitate selection of greenbug resistance in breeding through marker-assisted selection and provide information for map-based gene cloning. In the present study, microsatellite marker and deletion line analyses were used to map greenbug resistance genes in five newly identified wheat germplasms derived from Aegilops tauschii. Our results indicate that the Gb genes in these germplasms are inherited as single dominant traits. Microsatellite markers Xwmc157 and Xgdm150 flank Gbx1 at 2.7 and 3.3 cM, respectively. Xwmc671 is proximately linked to Gba, Gbb, Gbc and Gbd at 34.3, 5.4, 13.7, 7.9 cM, respectively. Xbarc53 is linked distally to Gba and Gbb at 20.7 and 20.2 cM, respectively. Xgdm150 is distal to Gbc at 17.9 cM, and Xwmc157 is distal to Gbd at 1.9 cM. Gbx1, Gba, Gbb, Gbc, Gbd and the previously characterized Gbz are located in the distal 18% region of wheat chromosome 7DL. Gbd appears to be a new greenbug resistance gene different from Gbx1 or Gbz. Gbx1, Gbz Gba, Gbb, Gbc and Gbd are either allelic or linked to Gb3.
