Millán-INIA is a variety of spring bread wheat (Triticum aestivum L.) originating from a cross carried out in the Wheat Plant Breeding Project of the Instituto de Investigaciones Agropecuarias (INIA), in the Centro Regional de Investigación Quilamapu in 1995. This is a spring wheat variety with an early to medium-early head emergence and upright growth habit in the seedling stage. The adult plant is low to medium height and varies between 75 and 90 cm, with a mean of 85 cm. The spike is white with long awns along its full length. The grain is large-sized, white, and vitreous. The weight of 1000 grains varies between 50 and 59 g. It was sown in mid-August at the Santa Rosa Experimental Station (36°31’ S; 71°54’ W), Chillán. Head emergence occurred 88 to 89 d after sowing, which is 2 to 3 d after Ciko-INIA. On average, Millán-INIA reached a yield similar to that of the var. Ciko-INIA. This line stands out for its good resistance to disease, high protein content (11.5% mean), high sedimentation value, and high W value.
