GONZALEZ GONZALEZ, Miguel; ZAMORA DIAZ, Mauro  e  SOLANO HERNANDEZ, Salomón. Agronomic and physical evaluation in advanced lines of malting barley. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.1, pp.159-171. ISSN 2007-0934.

Barley is one of the crops that offers a better production alternative in seasonal areas of the high valleys of Mexico. Its short cultivation cycle allows it to produce when it is not possible to do so in species such as maize and wheat. This grain can be used for various purposes: as human consumption, as animal fodder, and as malt in the brewing industry. In Mexico, barley is carried out principally for the production of grain with malt quality, using a six-row barley variety. So that a barley genotype can be considered a malting variety, it must fulfill various quality parameters. The Instituto Nacional de Investigaciones Forestales, Agrícolas y Pecuarias carries out investigations in order to generate genotypes that satisfy the quality parameters, are tolerant to diseases and have an excellent yield. With the objective of evaluating the agronomic behavior and quality in advanced lines of malting barley, 16 malting barley genotypes were established during the 2012 and 2013 agricultural cycles, under a 4 x 4 lattice design with four repetitions in five seasonal environments. The obtained results allowed for the identification of barley lines with malting potential. The lines M176, M177, M178, and M184 had a superior behavior for the evaluated localities and cycles with a yield of 3.8, 3.5, 3.9, and 4.0 t ha-1, respectively.
