Interpretive Summary: Soybean is a major agricultural crop in the United States. However, diseases can cause significant yield losses every year. Incorporating disease resistance into high-yielding cultivars represents a sustainable approach to manage diseases and minimize yield losses. ‘S15-10434C’ is a high-yielding conventional soybean cultivar and has been tested in 107 environments in southern states from 2016 to 2019 for yield and other agronomic traits. It is resistant to soybean cyst nematode, reniform nematode, peanut and southern root-knot nematodes, sudden death syndrome, frogeye leaf spot, and has field tolerance to Phytophthora root rot. In addition to its high yield potential and desired seed protein content, ‘S15-10434C’ has broad adaptation across southern states. It is an excellent choice for southern growers.

Technical Abstract: ‘S15-10434C’ is a maturity group V high-yielding conventional soybean [Glycine max (L) Merr.] cultivar developed and released in 2019 by the University of Missouri – Fisher Delta Research Center Soybean Breeding Program. ‘S15-10434C’ was developed following conventional breeding from a cross between ‘S11-17025C’ and ‘S05-11482’ which are Missouri soybean lines. ‘S11-17025C’ is a high yielding cultivar with resistance to multiple diseases while ‘S11-14954’ is a line with high-yield potential and SCN resistance, developed by the University of Missouri soybean breeding program. Before release,’ S15-10434C’ was tested in 107 environments in Missouri and other southern states from 2016 to 2019 for yield and other agronomic traits. On average, ‘S15-10434C’, yielded 4102 kg ha-1 which is higher than the all tests mean of 3907 kg ha-1. ‘S15-10434C’ seed contains 407 g kg-1 protein and 217 g kg-1 oil on dry seed weight basis. It exhibits relative maturity of 5.5, determinate growth habit, purple flowers, tawny pubescence and tan pod wall. Seeds are yellow with intermediate luster and black hila having seed weight of 13.1 g 100-1 seed. ‘S15-10434C’ is 76 cm tall with resistance to lodging. It is resistant to soybean cyst nematode (races 1, 2, 3, 5 & 14), reniform nematode, peanut and southern root knot nematodes, sudden death syndrome, frogeye leaf spot, and has field tolerance to Phytophthora root rot. This is also chloride excluder. In addition to its high yield potential and desired seed protein content, ‘S15-10434C’ has broad adaptation across southern states.
