Nematode resistant soybean cultivars

Plant parasitic nematodes are a major constraint to soybean production in the Southeast. Use of nematode-resistant cultivars is the only economically feasible method to control nematodes on soybean. In the soybean breeding project, UGA plant pathologists support the development and release of high-yielding soybean cultivars with resistance to multiple nematode species. The objective is to provide the expertise and phenotype screening support as needed for identification and evaluation of multiple-nematode-species resistance in soybean breeding lines at all phases of the development cycle. The team released a new high-yielding nematode-resistant Roundup-Ready soybean cultivar in 2013. G06-3182RR is an early maturity-group VII cultivar that possesses résistance to Southern and Javanese root-knot nematodes, race 3 of the soybean cyst nematode, and stem canker, a fungal plant disease. In statewide performance trials, G06-3182RR had yields that were 7 to 12 percent higher than commonly-grown MG VII soybean cultivars.
