Fragata F2025 is a new bread wheat variety developed for El Bajío, which was registered and protected in the National Catalog of Plant Varieties (CNVV, by its Spanish acronym) with the number TRI-216-030725. The cross that gave rise to it was carried out in the autumn-winter 2009-2010 cycle in Roque, Celaya, Guanajuato. The segregating generations were selected using the modified mass method. Its evaluation in yield trials began in the autumn-winter 2013-2014 cycle. Fragata F2025 is semi-dwarf and 90 cm tall; its vegetative cycle is intermediate, with 78 days to flowering and 125 days to physiological maturity. It is resistant to stripe or yellow rust, with only 5% severity, compared with 40, 60 and 100% exhibited by the Cortazar S94, Salamanca S75 and Luminaria F2012 varieties, respectively. In trials conducted across different planting dates, Fragata F2025 surpassed the control varieties Elia M2016 and Luminaria F2012 by 2.3 and 43.5%, respectively, and compared to Cortazar S94, the most planted variety in the El Bajío region, Fragata F2025 surpassed it by 15.3%. Under restricted irrigation, it was observed that, with two irrigations (0-55 days), the new variety obtained a yield of 4 519 kg ha-1, surpassing Cortazar S94 by 9.3%; with three irrigations (0-45 and 75 days), Fragata F2025 obtained a yield of 6 042 kg ha-1, surpassing the Cortazar S94 variety by 7.1%. Fragata F2025 has hard grains; its gluten is strong, with a W value of 313 x 10-4 J, and has a PL value of 6, which classifies the gluten of the new variety as strong tenacious.
