In Zacatecas forage characteristics of triticale varieties that could be an alternative for low rainfall areas are unknown. The objective was to determine the production and yield components of four varieties of triticale under rainfed conditions in Zacatecas. The experiments were evaluated during 2010 and 2012 in the Experimental Field Zacatecas. The experimental design was a complete randomized block with three replications, planting density was 120 kg ha^-1, planting dates were July 14, 2010 and July 18, 2012 and fertilization was 6040-00 of N-P₂O₅-K. Harvest was made at milky-doughy. In the production of green and dry fodder, the variety that stood out was Secano with 4685.3 and 1 876.7 kg ha^-1, respectively, only Pollmer presented similar yields (p> 0.05). Leave and spike showed differences (p< 0.05) between varieties, Secano stood out with 307.5 and 867.3 kg Ms/ha respectively, Pollmer had similar yields. There were no differences in stem (p> 0.05) between varieties. The variables that had a positive relationship (p< 0.001) with dry forage yield, were kilograms of leave (r= 0.85), stem (r= 0.77) and spike (r= 0.91). Varieties that excelled in the production of dry fodder was Secano and Pollmer, also, these had the highest yields of leaf and spike, therefore these varieties are a good alternative to make more efficient the production of dry matter in areas with low agricultural potential.
