Stink bugs are approaching key pest status in the southern soybean growing region of the US. The objective of this research was a rigorous evaluation of several soybean lines for resistance to stink bugs. The sources of resistance of the lines evaluated can be traced back to plant introductions 229358 and 227687. The following lines were evaluated: D86-11836, D86-11839, D86-11861, D96-1537, D96-1547, D96-1571, D96-3179, D96-3180, D96-3180, D82-6212, and the resistance standards IAC100 and GATIR 81-296, and the susceptible standard 'Davis'. Field results showed that the most resistant lines evaluated here were comparable to the resistant standard, IAC100. Population growth parameters of Nezara viridula cohorts feeding on resistant and susceptible lines and cultivars were evaluated in the laboratory. Population growth was lowest for cohorts feeding on D96-1537, IAC100, GATIR 81-296, D96-3179, and D86-11839. Considering both agronomic and resistance traits, the highest ranking lines were D96-1537 and D96-3179.
