‘Kiron INIA’ is a new wheat cultivar (Triticum aestivum L.) developed by the National Wheat Program at the Regional Experimental Center (CRI) Carillanca of the National Institute of Agricultural Research (INIA). The cultivar has medium plant height and late cycle; it is resistant to yellow rust (Puccinia striiformis West. f. sp. tritici Erikss) and oidium (Blumeria graminis D.C. f. sp. tritici Marchal), and moderately sensitive to leaf rust (Puccinia triticina f. sp. tritici Erikss y Henn) and septoria (Mycosphaerella graminicola (Fuckel) Sand). It is a high yielding winter wheat with good quality characteristics for direct baking, containing an allele of tolerance to soil acidity inherited from a parent. Its leaves are pale green, with a semi-erect flag leaf, with abundant cerosity (glaucosity) in the beam. The spike is white, decumbent, parallel in shape, high density, compact, with awns along its full length. The grain is round in shape, medium in size, and pale red in color. The height of the adult plant varies between 95 cm and 105 cm, with an average of 100 cm, and with a stem of very good resistance to lodging. It is a high yielding cultivar (12.9 t ha-1) exceeding the commercial check in different localities and seasons.
