‘Alsen’ (Reg. no. CV-997, PI 615543), is a hard red spring wheat (HRSW) (Triticum aestivum L.) developed at North Dakota State University (NDSU) and released by the North Dakota Agricultural Experiment Station (NDAES) in July 2000. Alsen was released because it combines resistance to Fusarium head blight (FHB) [caused by Fusarium graminearum Schwabe (teleomorph Gibberella zeae (Schwein.) Petch)], high grain yield, and excellent end-use quality for the domestic and export wheat markets. Alsen is an awned, medium-early maturing, and semidwarf HRSW. The spike is awned, middense, tapering to elliptical in shape. The awns are white and are 8 to 10 cm in length. The glumes of Alsen are medium and yellow with elevated shoulder and acuminate beak. The glumes width and shoulder length are medium. The kernels are hard, red, and oval; the germ is medium; and the brush is medium long. The crease is mid-deep and mid-wide and the cheek is angular. Alsen has a lax spike type with plant height (78 cm) similar of to Reeder and Grandin (80 cm); 12 and 14 cm shorter than Parshall and Keene; and 3 cm taller than ‘HJ98’ (PI 608723). The number of days from planting to heading of Alsen (61 d) is similar to Grandin, Reeder, and Parshall but 4 d earlier than ‘McVey’ (PI 612966) (Bush et al., 2001). Under environmental conditions favorable to grain shattering, Alsen may show some of shattering (less than 5%) comparable to Reeder, HJ98, and Gunner, while no shattering was observed on Keene, McVey, and Parshall. On a 1-to-9 scale for lodging score (LS) where 1 is resistant to lodging and 9 is very susceptible to lodging, Alsen is has good straw strength (LS = 1) comparable to Reeder (LS = 1.3), Keene (LS = 1.1), and Gunner (LS = 1.3) but better than McVey (LS = 4.5).
Alsen was derived from the "ND674//ND2710 (PI 633976)/ND688" cross made at NDSU in the spring of 1995. ND674 (‘Grandin’(PI 531005)*2/‘Glupro’ (PI 592759)) and ND688 (Grandin/3/IAS20*4/H567.71//‘Amidon’ (PI 527682)) are two hard red spring experimental lines that have good adaptation to North Dakota wheat growing conditions and good end-use quality. ND674 is derived from Glupro, a HRSW cultivar released in 1995 by the NDAES for its very high grain protein content derived from Triticum dicoccoides (Koern. ex Asch. & Graebner) Aarons. ND2710 (Frohberg et al., 2004) is a hard red spring germplasm developed from the cross ND2603/Grandin made in 1991. Grandin is a HRSW cultivar released by the NDAES in 1989 and ND2603 was developed from the cross ‘Sumai3’ (PI 481542)/‘Wheaton’ (PI 469271) made in 1987. Sumai3, a spring wheat from China, is arguably the most used source of resistance to FHB in the world (Wilcoxson, 1993; Rudd et al., 2001).
