What is Combining ability for beet armyworm, Spodoptera exigua, resistance and horticultural traits of selected Lycopersicon pennellii-derived inbred backcross lines of tomato about?
## Abstract Ten selected inbred backcross lines (IBL), from a __Lycopersicon esculentum__ cv.‘Peto 84’×__Lycopersicon pennellii__ IBL population, with resistance to beet armyworm (BAW), Spodoptera exigua, higher fruit mass and fruit yield, were crossed with eight elite cultivated L. __esculentum__ inbred lines in a Design II mating design. Three elite inbreds were also crossed to ‘Peto 84′, the IBL recurrent parent, as a control for combining ability. Field plots of all resulting F~1~ progenies and control cultivars were inoculated with BAW eggs and evaluated for resistance to BAW, fruit mass, fruit yield, vine size and maturity at three field locations. Reductions in fruit damage by BAW were found in four of the 10 IBL F~1~ progenies. Significant male and female general combining ability (GCA) estimates for BAW resistance were observed, but significant specific combining ability for BAW resistance was not detected. The fruit mass of F~1~ hybrids was significantly lower than large‐fruited controls, but was not significantly different from elite inbred by ‘Peto 95’F~1~ hybrids. Selection based on inbred performance identified IBL with positive GCA for BAW resistance and yields in De
