The Lleuque-INIA spring durum wheat variety (Triticum turgidum var. durum L.) originated from a cross carried out by the Instituto de Investigaciones Agropecuarias (INIA), National Wheat Program, in the Centro Regional de Investigación La Platina, Santiago, Chile, in 1993. This variety has an upright growth habit in the seedling stage; the adult plant is of medium height and varies between 80 and 90 cm. The spike is medium-sized, white, and exhibits long whitish awns along its full length. The grain is large-sized, elongated, golden yellow, and vitreous. The variety was sown in mid-August in the Santa Rosa Experimental Station (36°31’ S; 71°54’ W), Chillán, head emergence occurred between 89 and 91 d after sowing, and was 6 to 8 d later than ‘Llareta-INIA’ and ‘Corcolén-INIA’. In La Platina, ‘Lleuque-INIA’ had a mean yield of 16.7 and 20.8% higher than vars. Llareta-INIA and Corcolén-INIA, respectively, whereas the yield was higher in Chillán by 10.3 and 10.1%, respectively. On the other hand, in Yungay located in the Ñuble foothills, ‘Lleuque-INIA’ yield exceeded ‘Llareta-INIA’ by 13.07% and var. Corcolén-INIA by 16.97%. In Humán, var. Lleuque-INIA yield exceeded the control vars. Llareta-INIA and Corcolén-INIA by 15.23 and 24.03%, respectively. Lleuque-INIA variety is a type of wheat with good hectoliter weight, good wet gluten content (%), and a protein value mean fluctuating between 10.47 and 12.3%.
