Registration of ‘S16‐11651C’, a conventional soybean cultivar with high yield, resistance to multiple diseases, and broad adaptation

Abstract

Abstract‘S16‐11651C’ (Reg. no. CV‐549, PI 699631) is an early maturity group (MG) V, semi‐determinate, conventional, high‐yielding soybean [Glycine max (L) Merr.] cultivar developed and released in 2020 by the University of Missouri–Fisher Delta Research Center Soybean Breeding Program. High global demand for soybean oil and animal feed and U.S. mid‐southern growers’ interest in early‐MG V conventional cultivars with high yield potential, desired protein and oil content, and broad disease resistance motivated the development and release of S16‐11651C soybean. S16‐11651C was tested in 94 environments in Missouri and 11 other mid‐southern states from 2017 to 2020 for yield and other agronomic traits. On average, S16‐11651C yielded 4,327 kg ha–1, which is 292 kg ha–1 higher than the all‐tests mean of 4,035 kg ha–1. S16‐11651C seed contains 413 (41.3%) and 220 (22%) g kg–1 of protein and oil, respectively, on a dry weight basis. S16‐11651C exhibits relative maturity of 5.3 and has white flowers, tawny pubescence, and tan pod walls. The seed is yellow with intermediate luster and black hila with a weight of 13.5 g 100–1 seed. S16‐11561C is 88 cm tall on average with resistance to lodging. It is resistant to cyst nematode (races 1, 2, and 5 with moderate resistance to race 3), peanut and southern root‐knot nematode, reniform nematode, brown stem rot, charcoal rot, and purple seed stain and moderately resistant to Phomopsis seed decay. S16‐11561C has the capacity to exclude chloride. In addition to its high yield potential, high seed protein and oil content, and early maturity, S16‐11561C has exhibited broad adaptation across mid‐southern states.
