VELASCO LOPEZ, José Luis et al. Biomass and grain yield in triticale varieties in the Mexicali valley. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.5, pp.1097-1109.  Epub Oct 03, 2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v11i5.2293.

The Mexicali valley is an important region in the production of meat and milk of bovine origin with acceptance in other countries, mainly the United States of America, Japan and Korea. For this reason, quality forage is required to feed cattle such as triticale, used in various areas of Mexico; however, in the Mexicali valley, there is no information on agronomic behavior. The objective of this study was to evaluate the dry biomass and grain yield of 10 varieties of triticale in the 2014-2015 and 2015-2016 A-W cycles, in the Mexicali valley. The experimental design was randomized complete blocks with three replications. 10 varieties of triticale of different growth types were evaluated, 4 spring, 2 facultative, 4 winter and oats. In the first evaluation cycle, the highest total biomass production corresponded to the variety AN105 and AN125 with 10.7 and 10.5 t ha-1, in grain yield the varieties AN105, AN38, AN125, AN31B, ABT and Eronga produced from 7.3 to 5.4 t ha-1. For the second cycle, the superior varieties in total biomass were AN31B, ABT, AN38, AN34, AN31P and Eronga with 6 to 4.9 t ha-1 and in grain yield AN38, AN123, Eronga and AN125 from 4.1 to 3.1 t ha-1. In conclusion, the winter varieties AN31B and AN34 showed potential for the production of total biomass, the facultative variety AN38 and the spring varieties AN125 and Eronga, showed superiority in grain yield in the two evaluation cycles.
