CHAVEZ-VILLALBA, Gabriela et al. Patronato Oro C2008, durum wheat with industrial quality for northwestern Mexico. Rev. Mex. Cienc. Agríc [online]. 2012, vol.3, n.7, pp.1441-1446. ISSN 2007-0934.

Patronato Oro C2008 is a variety of durum wheat (Triticum turgidum ssp. durum) developed in Norman E. Borlaug Experiment Station (CENEB) through a collaborative project between the National Research Institute for Forestry, Agriculture and Livestock (INIFAP) and the International Maize and Wheat Improvement Center (CIMMYT). Its growth habit during spring and resistance to prevalent races of rust in the northwest Mexico, favor the crop producing areas in the States of Sonora, Baja California, Sinaloa and Baja California Sur. Experimentally it's identified as the resultant of the crossing SULA/ AAZ_5//CHEN/ALTAR84/3/AJAIA_12/F3LOCAL(SEL. ETHIO. 135.85)//PLATA_13/4/ARMENT//SRN_3/ NIGRIS^_4/3/CANELO^_9.1 with the historical selection of CDSS02Y00390S-0Y-0M-8Y-0M. Patronato Oro has the registration number 110-240209 of the National Catalogue of Plant Varieties of the National Seed Inspection and Certification. Its grain yield averaged 5.5 t ha^-1 in experimental plots managed with three auxiliary irrigations, planted between November 15^th and January 1^st between, 2006- 2007 and 2008-2009 cycles. In plots with farmer cooperators in southern Sonora, Patronato Oro C2008 averaged 7.2 t ha^-1 in 2008-2009 growing season, so it represents a new option for durum wheat farmers in the northwest. However, the main attribute of this variety is represented by its high level of pigmentation, 28.4 points, estimated with a Minolta colorimeter.
