Abstract only
Western Siberia is a leading area for production of high quality spring wheat. However, in recent years there has been an increased threat of stem rust, which can cause grain yield losses of up to 50%. The need for resistance to race Ug99 is a further problem for the region. Lines with Sr9e, Sr24, Sr25, Sr26, Sr27, Sr31, Sr33, Sr35, Sr36, Sr38, Srdp-2, Sr7a + Sr12 + Sr and varieties Norm, Bacanora, and Cham 10 were highly resistant in 2009-2011. Lines with genes Sr9g, Sr11, Sr13, Sr26, Sr32, Sr2 + Sr23, Sr26 + Sr9g, Sr33 + Sr5 and varieties Cham 6, Gemmeiza-9, Chamran, Inqalab 91, Aguila l, and Altar 84 durum gave variable reactions. None of 164 varieties from the Siberian Agricultural Research Institute was resistant when tested in Kenya. The most virulent pathotypes in our region, TFR/NL and KKH/DG, were virulent for 8 and 7 respectively, of the 20 Sr genes. A spring wheat collection with resistance to Western Siberian Pgt races and to Ug99 was assembled for breeders in the region.
