摘要
“MN-Rothsay”(Reg。否。CV-1208, PI 702731)硬红春小麦（Triticum aestivum）因其高产和抗倒伏，于2022年由明尼苏达大学农业试验站发布。MN-Rothsay是株高低于平均水平的中晚熟品种，含有半矮化等位基因Rht-B1b和Rht24b。MN-Rothsay的抗倒伏性与2013年发布的“linkt”相似，linkt是明尼苏达州2016年至2020年种植最广泛的品种，主要是因为其优越的抗倒伏性。MN-Rothsay对赤霉病（主要由小麦赤霉病引起）具有中等抗性，对引起叶锈病（小麦锈病）和茎锈病（小麦锈病）的流行病原体具有良好的抗性。:珀耳斯。p.p tritici Eriks,E.

Registration of ‘MN-Rothsay’ spring wheat with high grain yield and lodging resistance
‘MN-Rothsay’ (Reg. No. CV-1208, PI 702731) hard red spring wheat (Triticum aestivum) was released by the University of Minnesota Agricultural Experiment Station in 2022 because of its high grain yield and lodging resistance. MN-Rothsay is a medium-late maturity cultivar with below average plant height, containing the semi-dwarfing alleles Rht-B1b and Rht24b. The lodging resistance of MN-Rothsay is similar to ‘Linkert’, a 2013 release that was the most widely grown cultivar in Minnesota from 2016 to 2020, largely due to its superior lodging resistance. MN-Rothsay has moderate resistance to Fusarium head blight (caused primarily by Fusarium graminearum Schwabe), good resistance to prevalent races of pathogens causing leaf rust (Puccinia triticina Eriks.) and stem rust (P. graminis Pers.: Pers. f. sp. tritici Eriks. & E. Henn.), and is well-adapted to the north central United States.
期刊介绍：
The Journal of Plant Registrations is an official publication of the Crop Science Society of America and the premier international venue for plant breeders, geneticists, and genome biologists to publish research describing new and novel plant cultivars, germplasms, parental lines, genetic stocks, and genomic mapping populations. In addition to biomedical, nutritional, and agricultural scientists, the intended audience includes policy makers, humanitarian organizations, and all facets of food, feed, fiber, bioenergy, and shelter industries. The scope of articles includes (1) cultivar, germplasm, parental line, genetic stock, and mapping population registration manuscripts, (2) short manuscripts characterizing accessions held within Plant Germplasm Collection Systems, and (3) descriptions of plant genetic materials that have made a major impact on agricultural security. Registration of plant genetic resources, item (1) above, requires deposit of plant genetic material into the USDA ARS National Plant Germplasm System prior to publication.
