Abstract:
‘Mattern’ (Reg. No. CV-1092, PI 665947) hard winter waxy wheat (Triticum aestivum L.) was developed cooperatively by the USDA–ARS and the Nebraska Agricultural Experiment Station and released in 2012. Mattern has red grain color and waxy (amylose-free) endosperm starch. It was released primarily for its unique end-use quality attributes and for grain yield competitive with currently grown Nebraska adapted cultivars. The waxy starch is conditioned by the presence of three naturally occurring mutations that eliminate production of the enzyme granule-bound starch synthase. Granule-bound starch synthase synthesizes amylose in typical wheats and other cereal crops. Mattern was tested experimentally as NX04Y2107 and was selected from the cross NW98S061/99Y1442.
