Kipa-INIA is a spring wheat variety (Triticum aestivum L.) originated 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 (36°31’ S; 71°54’ W) in 1993. It has an upright growth habit in the seedling stage. The adult plant is low to medium height and varies between 90 and 95 cm. The spike is white with long awns along its full length. The grain is ovate, white, and vitreous. It was sown in mid-August in the Santa Rosa Experimental Field, Chillán, head emergence occurred 90 to 95 d after sowing, i.e. is 4 to 6 d before ‘Domo-INIA’. On the mean, ‘Kipa-INIA’ sown under irrigation conditions reached a yield of 11.7% higher than the control var. Domo-INIA, and 18.1% higher in dryland soils.
