Registration of high yield conventional soybean ‘S17‐2193’ with resistance to multiple diseases

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.
