RAMIREZ VAZQUEZ, Jessica et al. Evaluation of varieties and even lines of bread wheat temporal in Valles Altos. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.3, pp.655-667. ISSN 2007-0934.

In order to study the agronomic performance and phytopathological uniform lines and varieties of bread wheats for temporal area of the high valleys of Mexico, eight varieties released by INIFAP in different time lines and two new varieties candidates they were evaluated. They were tested during 2012 and 2013 in the Spring-Summer cycle in eight locations under the Valles Altos blocks randomized design with two replications. In general, advanced lines Don Carlos "S" and Mona "S" showed the highest yields, lower incidence of yellow rust, leaf rust, leaf spot diseases and had lower biological cycle in the three types of environments, expressing a range broad adaptability. The varieties showed good behavior in these environments were Nana F2007 and Altiplano F2007, while the older varieties as Romoga M87 and Galvez M87 were the lowest performing, indicating that the progress of breeding for rainfed wheat for grain yield it has been gradual and ascending.
