Yellow rust resistant, new improved winter wheat genotypes for Central Asia and the Caucasus - 2013 - p. 251
Abstract only
Yellow (stripe) rust is the most important disease constraint of winter wheat in Central Asia 1nd the Caucasus (CAC). There were severe epidemics of yellow rust in many parts of the CAC in 2013. A few widely grown varieties, which were moderately resistant during 2009 and 2010 epidemics, became highly susceptible to yellow rust in 2013. A few varieties ready for release by the State Variety Testing Commission (SVTC) showed susceptibility to yellow rust in 2013. However, several advanced breeding lines evaluated in the nurseries originating from International Winter Wheat Improvement Program showed high level of resistance to yellow rust. A few winter wheat lines, selected for high yield, and satisfactory quality and agronomic characters in the previous years were resistant to yellow rust across the region in 2013. One auperior line (Ymh/Hys//Hys/Tur3055/3/Dga/4/Vpm/Mos/S/S/TAM200/Kauz, TCl-02-138: ?OAP-OAP-7AP-OAP-SA-OAP), resistant to yellow rust will be submitted to th,e SVTC in Tajikistan In 2013. Another resistant line (Attila/2*Pastor//Bulk Sein OOFS-43-11, OCW02S557S: -OOK-OE-6E-OE -lE -OE) is going to be submitted to the SVTC in Uzbekistan in 2013. In Georgia, one line (Burbot-6/Cardinal, TCl-01-13: -OAP-OAP-8AP-OAP-2AP-OAP) resistant to yellow rust and leaf rust will be submitted for registration by the State Agency. The findings of this study provide valuable Information on yellow rust resistance and performance of the internationally important winter wheat genotypes. This information could be useful for the national and international winter wheat improvement programs in either further evaluation of the resistant lines for varietal identification or using them as parents in the crossing.
