Resistance to the Ug99 group of races of the stem rust fungus Puccinia graminis f. sp. tritici is limited in winter wheat (Triticum aestivum L.) germplasm adapted to the Great Plains of the United States. Our objective was to generate regionally adapted hard winter wheat germplasm with combinations of adult plant resistance genes that are expected to provide durable resistance. KS14U6380R5 (Reg. no. GP‐1043, PI 689115), KS16U6380R10 (Reg. no. GP‐1044, PI 689116), and KS16U6380R11 (Reg. no. GP‐1045, PI 689117) were derived from backcrosses of the hard white winter wheat germplasm KS05HW14 to the stem rust‐resistant Kenyan spring wheat cultivar ‘Kingbird’. KS14U6380R5, KS16U6380R11, and KS16U6380R10 were developed by pedigree selection and were initially evaluated as U6380‐11‐2R‐0A, U6380‐210‐2R‐0A, and U6380‐148‐4R‐2T, respectively. The germplasms were developed by the USDA‐ARS and jointly released with the Kansas State University Agricultural Experiment Station. These germplasms provide parents for development of hard winter wheat cultivars with durable resistance to stem rust.

硬白冬小麦种质KS14U6380R5，KS16U6380R10和KS16U6380R11与成年植物对茎锈病的抗性注册

对Ug99组的茎锈菌真菌Puccinia graminis f具有抗性。sp。小麦冬小麦是有限的（小麦L.）种质适应美国大平原。我们的目标是生成具有成年植物抗性基因组合的，适应当地情况的硬质冬小麦种质，这些基因有望提供持久的抗性。KS14U6380R5（Reg。编号GP‐1043，PI 689115），KS16U6380R10（Reg。编号GP‐1044，PI 689116）和KS16U6380R11（Reg。编号GP‐1045，PI 689117）源自硬白的回交冬小麦种质KS05HW14，耐茎锈病的肯尼亚春小麦品种'Kingbird'。KS14U6380R5，KS16U6380R11和KS16U6380R10是通过血统选择开发的，最初分别评估为U6380‐11‐2R‐0A，U6380‐210‐2R‐0A和U6380‐148‐4R‐2T。种质由USDA-ARS开发，并与堪萨斯州立大学农业实验站联合发布。
