Commercial cultivar Samayoa C2004 was developed at Yaqui Valley Experimental Station through a collaborative project between National Research Forestry, Agriculture and Livestock Institute and International Maize and Wheat Improvement Center. The pedigree and selection history is SOMAT_4/INTER_8, CDSS95B00181S-0M-1Y-0B-1Y-0B-0Y-0B-14EY-0Y. This semi-dwarf cultivar is resistant to leaf rust,and the quality characteristics for pasta-making are better than commercial control cultivar Júpare C2001, so that it becomes a better option for international export for wheat producers from northwestern Mexico. During crop seasons of evaluation 2001-2002 to 2003-2004, Samayoa showed a range of grain yield of 5.2 to 8.3 t ha^-1 depending on region where it was evaluated (Experimental Station in the Yaqui Valley, Caborca Region, Hermosillo Coast in State of Sonora and Fuerte Valley in Sinaloa). This cultivar has the registration 1733-TRI-062-030505/C in the catalogue of cultivars feasible for registration. Seed may be purchased through several seed companies.
