Abstract | Yellow spot (syn. tan spot), caused by Pyrenophora tritici-repentis , is an important foliar disease of wheat in Australia that causes losses exceeding 50 % when conditions are favourable for disease development. Although good progress has been made internationally to understand yellow spot resistance, relatively few resistance genes have been identifi ed and mapped in Australian germplasm and only one (tsn1 on chromosome 5BL) is in general and known use in Australian breeding programs. Although tsn1 is an important yellow spot resistance gene, it doesn’t explain the full spectrum of resistance and there is a significant opportunity to enhance expression of yellow spot resistance through identification of resistance factors other than tsn1 . Six doubled haploid (DH) mapping populations (five of which were fixed for tsn1) were screened for yellow spot resistance at the seedling/tillering and adult plant stages at the Department of Agriculture and Food, Western Australia (DAFWA) and the Department of Environment and Primary Industries Victoria (DEPIVic) from 2009 to 2012. Four of the above populations were screened at the Department of Agriculture, Fisheries and Forestry Queensland (DAFFQ). Frequency distribution of individuals within each population for various levels of yellow spot resistance was continuous indicating that resistance is conditioned by several genes with partial effects. A few lines within each population consistently showed high levels of resistance probably resulting from a combination of several genes with additive effects. Nine new loci for yellow spot resistance were mapped. |
