‘Flathead’ (Reg. no. CV‐1164, PI 693237) hard red winter (HRW) wheat (Triticum aestivum L.) was developed and released by the Montana Agricultural Experiment Station in 2019. Flathead was derived from a composite of two very closely related single crosses of the predominant cultivar ‘Yellowstone’ to stripe rust resistant source PI 640431, a hard white spring wheat backcross derivative of WA007900 that carries stripe rust all‐stage resistance genes Yr5 and Yr15. Flathead was developed using a modified bulk breeding method and selected as an F5:6 head row after phenotypic selection for stripe rust resistance at Kalispell, MT. Flathead was tested under the experimental number MT1564 in Montana yield trials from 2015 to 2019. Flathead is a high‐yielding HRW wheat cultivar with early maturity, short stature, medium grain protein concentration, excellent milling and baking quality, and a high level of all‐stage resistance to predominant races of stripe rust. Flathead was released for its early maturity, improved stripe rust resistance, and improved grain yield relative to other Montana‐adapted early heading cultivars.

“ Flathead”硬红冬麦的注册

“扁平头”(Reg。no。CV-1164,PI 693237)硬红冬小麦(Triticum aestivum L.)是由蒙大拿州农业试验站于2019年开发和发布的。扁平头是由两种非常复杂的混合物制成的。与主要品种'Yellowstone'的单交紧密相关,与条纹抗锈病源PI 640431密切相关,PI 640431是WA007900的硬白春小麦回交衍生品,带有条纹锈病全阶段抗病基因Yr5Yr15。扁平头是使用改良的大量繁殖方法开发的,并被选为F 5:6表型选择后的头排,MT的Kalispell的条纹防锈性能。Flathead已在2015年至2019年的蒙大拿州产量试验中通过实验编号MT1564进行了测试。Flathead是一种高产HRW小麦品种,具有早熟,矮小,中等谷粒蛋白质浓度,出色的制粉和烘烤品质,并且所有产品中的高水平对主要的条纹锈病具有抗性。与其他蒙大拿州适应的早抽穗品种相比,扁头的早期成熟,改善的抗条纹锈蚀性和提高的谷物产量被释放。
