Registration of ‘Henderson’ Soybean

Abstract

‘Henderson’ soybean [Glycine max (L.) Merr.] (Reg. No. CV‐509, PI 665225) was developed and released by the Alabama Agricultural Experiment Station in July 2011 as a mid–maturity group VIII (relative maturity 8.3) cultivar with high yield and oil content. Our objective was to develop a conventional (non–genetically modified [GM]) cultivar with high yield adapted to the southeastern United States. Henderson was developed by conventional breeding from the cross ‘NC‐Raleigh’ × G92‐1110 using single‐seed descent generation advance. A single F5:6 progeny row was bulked and tested for yield, agronomic traits, and disease reactions in trials in Alabama and across the southern United States. The average seed yield was significantly greater than for ‘Prichard RR’ in 2006 and 2007, greater than for ‘Cook’ in 2005 and 2006, and greater than for ‘N8001’ in 2008. Seed oil content was significantly higher than for Prichard RR and other checks. Henderson is moderately resistant to southern root‐knot nematode [Meloidogyne incognita (Kofoid and White) Chitwood] and susceptible to peanut root‐knot [M. arenaria (Neal) Chitwood] and soybean cyst nematode (Heterodera glycines Ichinohe) races 2, 3, and 14. It is resistant to southern stem canker [caused by Diaporthe phaseolorum var. meridionalis Fernández), and Soybean mosaic virus. Because of its high yield and non‐GM status, Henderson is a desirable cultivar for use in conventional or organic systems, as a parent for cultivar development, or for use in countries where GM crops are not allowed.
