VILLASENOR MIR, Héctor Eduardo et al. Valles F2015: new wheat variety for rainfed crops in Mexico. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.6, pp.1315-1320. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i6.1592.

Valles F2015 is a variety of bread wheat that was released by the Wheat Genetic Improvement Program of the INIFAP. The experimental line was obtained through the male sterility technique to facilitate the recurrent selection (EMFSR), which requires a source of male sterility, a recombinant population and the recurrent selection, in such a way that Valles F2015 is the first variety that generates in Mexico through EMFSR. It is a variety of spring habit, intermediate to late cycle, tall and tolerant to lodging. The genealogy of the variety is: PAMDOLY.PABG (Late.C4). Valles F2015 was evaluated from 2011 to 2015 in 79 different conditions under temporary, comparing with 11 control varieties, which exceeded in grain yield of 15% (Altiplano F2007) to 35% (Nana F2007), showing good behavior in any environment of temporary. Under the natural incidence of blight, leaf spots and yellow rust, Valles F2015 was more resistant than the control varieties and was the variety that showed the lowest loss in yield (9% and 10%, respectively) when evaluated with and without protection with fungicides. Valles F2015 is hard grain that produces a strong gluten mass, suitable for mechanized or artisan baking and to be used in mixtures to improve flours with little force or tenacious. This new variety is recommended in all areas producing rain wheat in early to intermediate sowings.
