520 _aWheat is the staple food and main source of caloric intake for 8 million people in Tajikistan. Therefore, it's high importance to have an in-country breeding program in collaboration with International Centers, in order to maintain food security for growing population in country. The breeding activities carried out by the national wheat breeding program, and it has resulted in a number of high yielding, yellow rust and stem rust resistances facultative/winter and spring bread wheat lines being identified through multi-location yield trials. Yellow rust and stem rust of wheat continues to cause severe damage locally and globally. In this context the identification of yellow rust and stem rust resistance genes present in cultivars currently cultivated, advanced lines and landraces are important information for national wheat breeding program. The objective of this study was to postulate,, using filed screening and seedling resistance tests. We evaluated materials for yellow rust response in the field in Tajikistan, and seedling reactions to a worldwide panel of isolates were assayed at the Global Rust Reference Center in Denmark. Stem rust response in the field at Njoro, Kenya, and seedling reactions to Pgt races TTKSK, TIKST, TITSK, TRTIF, TPMKC, TTTIF, QTJHC and RKQQC at the USDA-ARS Cereal Disease Laboratory were evaluated. Gene postulation and ad'-"lt stage testing indicated that resistance genes Yrl, Yr2, Yr6, Yr7, YrB, Yr9, Yr17, and Yr27 for yellow rust, and the SrlO and Sr31 for stem rust were identified. Moreover, several lines were highly resistant and likely possess novel genes for yellow rust and stem rust resistances.
