To meet the growing demand for high‐oleic soybean [Glycine max (L.) Merr.] cultivars, the University of Missouri‐Fisher Delta Research, Extension, and Education Center soybean breeding program has developed and released ‘S16‐16641R’ (Reg. no. CV‐559, PI 703070). It is a productive maturity group 4‐late (relative maturity 4.8), glyphosate‐tolerant (Roundup Ready 1) cultivar with high‐oleic content (81.7%) and reduced linolenic acid content (4.3%). In addition to its high‐yield potential, S16‐16641R has a broad disease resistance including soybean cyst nematode (Heterodera glycines Ichinohe) races 1 (HG Type 2.5.7), 2 (HG Type 1.2.5.7), 3 (HG Type 5.7), and 5 (HG Type 2.5.7), southern root‐knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood], reniform nematode (Rotylenchulus reniformis Linford & Oliveira), and stem canker (caused by Diaporthe aspalathi Jansen, Castlebury & Crous). It is a chloride excluder with tolerance to high salt field conditions. It was tested in 43 environments across eight states from 2017 to 2020, with an overall relative yield of 99.9% of the mean of the check. The high‐oleic acid content and comprehensive disease resistance combined with broad adaptability and high yield potential across multiple environments make S16‐16641R a promising soybean cultivar for growers to potentially maximize profits by receiving a premium price for high‐oleic oil content. Core Ideas S16‐16441R is high in oleic acid in soybean seed oil. S16‐16641R has reduced linolenic acid in soybean seed oil. S16‐16641R is tolerant to the herbicide glyphosate.
