Abstract
‘S17-2193’ (Reg. no. CV-565, PI 707954) is a high-yielding late maturity group IV (relative maturity of 4.7), conventional soybean [Glycine max (L.) Merr.] cultivar developed and released in 2022 by the University of Missouri Fisher Delta Research, Extension, and Education Center. S17-2193 was tested in over 88 environments (40 environments for preliminary, advanced, cooperative and uniform tests; and 48 environments for soybean state variety tests) from 2018 to 2021 in 10 states: Alabama, Arkansas, Illinois, Kansas, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, and Tennessee. Results showed that S17-2193 was well adapted across the mid-South United States. This soybean cultivar has overall mean yield of 4336 kg ha−1, being 104% of non Xtend check overall. S17-2193 averaged 226 g kg−1 oil concentration, which was significantly higher than the conventional soybean cultivar ‘Ellis’. In addition to its high yield potential and high oil concentration, S17-2193 is moderately susceptible to soybean cyst nematode (Heterodera glycines Ichinohe) race 2 (HG Type 1.2.5.7), and resistant to race 3 (HG Type 0). It is also moderately resistant to stem canker (caused by Diaporthe phaseolorum var. meridionalis F. A. Fernández), and resistant to charcoal rot (caused by Macrophomina phaseolina Tassi Goid). S17-2193 is a promising maturity group IV cultivar for mid-Southern growers to improve profits by receiving a premium price where conventional soybean is in demand.
“肌力- 2193”(Reg。否。CV-565, PI 707954)是高产晚熟IV组（相对成熟度4.7），常规大豆[甘氨酸max (L.)]。稳定。密苏里大学费舍尔三角洲研究、推广和教育中心于2022年开发并发布了该品种。S17-2193在超过88个环境中进行了测试(40个环境进行了初步、高级、协作和统一测试；从2018年到2021年，在阿拉巴马州、阿肯色州、伊利诺伊州、堪萨斯州、肯塔基州、路易斯安那州、密西西比州、密苏里州、北卡罗来纳州和田纳西州等10个州进行48个大豆州品种试验环境。结果表明，S17-2193在美国中南部适应良好。该大豆品种的总平均产量为4336公斤/公顷，占未扩展检查总产量的104%。S17-2193的平均油浓度为226 g kg−1，显著高于常规大豆品种Ellis。S17-2193除具有高产潜力和高油浓度外，对大豆囊线虫（Heterodera glycines Ichinohe） 2号小种（HG型1.2.5.7）有中度敏感性，对3号小种（HG型0）有抗性。它还对茎溃疡病（由Diaporthe phaseolorum var. meridionalis f.a. Fernández引起）和木炭腐病（由Macrophomina phaseolina Tassi Goid引起）具有中等抗性。S17-2193是一种很有前途的成熟IV组品种，对于中南部种植者来说，通过在常规大豆需求大的地方获得溢价来提高利润。
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.
