INIFAP makes available to irrigated wheat producers the variety ‘Conatrigo F2015’, obtained in the Wheat Genetic Improvement Program in the Valle de Mexico Experimental Field. The parents Thelin and Weebill were crossed in El Batan in S-S/2001, the F1 was backcrossed to WEEBILL in Cd. Obregon in A-W/2001-2002. The F1 TOP cross (CGSS02Y00079T) was sown in El Batan in S-S/2002, an indefinite number of plants were harvested in mass (099B), this procedure was followed alternately in El Batán, Atizapán and Cd. Obregon until F5 was planted in Cd. Obregon, Son. In A-W/2004-2005, plant No. 6 (6Y) was individually selected and harvested, obtaining the line that gave rise to the variety. From the A-W/2007-2008 cycle to A-W/2014-2015 it was evaluated by INIFAP in ten states and up to 120 different conditions. It is genealogy is Thelin/2*Wbll1 and pedigree, CGSS02Y00079T-099B-099B-099Y-099M-6Y-0B. the definitive registration number is TRI-174- 231117 and breeder’s title 1895. It has the genes Lr24 and Lr46 that give resistance to the races of leaf rust present in Mexico. It has the Yr29 and Yr30 genes that confer resistance to yellow rust in adult plants. It surpassed in yield from 3% (Kronstad F2004) to 32% (Palmerin F2004) in normal irrigation. It is hard grain with strong dough (W> 300 J × 10-4), extensible (PL< 1), bread volume greater than that of Kronstad F2004, with dough suitable for mechanized breadmaking or as a soft dough improver and tenacious.
