Data and planting density on the production and quality seed the triticale (X Triticosecale Wittmack). The objective of this study was to evaluate the effects of sowing dates and seeding rates on triticale seed yield and quality. This work was performed during the autumn-winter season in 2006-2007, at the research station of The Technological Institute of Roque, located at km 8 of the highway Celaya-Juventino Rosas, Celaya, Guanajuato, Mexico. We used three cultivars of triticale of different genetic origin (Roque I, AN-31 and AN-105) with one formula per hectare of 120-100-100, NPK. Three sowing dates were evaluated, November 9, November 23, and December 7, and five seeding rates at each planting date, 50 kg/ha, 75 kg/ha, 100 kg/ha, 125 kg/ha and 150 kg/ha. The variables evaluated were plant height, ear length, seed yield, vigor, and germination. The experimental design was a randomized complete block design with a factorial arrangement. The optimal sowing date for seed production was November 9, resulting in a yield of 5,305 t/ha. This treatment resulted in the highest values for ear length, plant height, vigor, and germination. When selecting important traits to produce high quality seed, through sowing density, the highest plant population was obtained with 125 kg/ha resulting in a yield of 3,834 t/ha, vigor of 82.0% and germination of 89.83%.
