FUENTES-DAVILA, Guillermo et al. Cevy Oro C2008, durum wheat with resistance to leaf rust. Rev. Mex. Cienc. Agríc [online]. 2012, vol.3, n.2, pp.403-408. ISSN 2007-0934.

The commercial variety CEVY Oro C2008 was developed at the Norman E. Borlaug Experimental Station in a collaboration between INIFAP and CIMMYT, for the wheat-producing areas of the states of Sinaloa, Sonora, Baja California Sur, and Baja California in Mexico. Its pedigree is SCRIP_1//DIPPER_2/BUSHEN_3/4/ ARMENT//SRN_3/NIGRIS_4/3/ CANELO_9.1, CDSS02Y00381S-0Y-0M-19Y-0M and its selection history is CDSS02Y00381S-0Y-0M-19Y-0M. CEVY Oro C2008 has the registration TRI-111-240209 in the catalogue of cultivars feasible for registration. This wheat variety has a springtime growth habit and is resistant to leaf rust (Puccinia triticina), with an experimental average grain yield of 5.6 t ha-¹ with three complementary irrigations, in four sowing dates. CEVY Oro C2008 averaged 7.1, 7.4, and 7.2 t ha-¹ in 2008-2009, 2009-2010, and 2010-2011, respectively, in commercial fields of cooperating wheat producers from southern Sonora; therefore, this cultivar is a new option of durum wheat for wheat producers of northwest Mexico.
