^aPosition of the QTL, in cM, referred to the linkage group

^bLogarithm of the odds (LOD); for all six traits a threshold of 3.6, corresponding to a genome-wide confidence level of 0.05, was estimated from permutation tests

^cNegative values indicate that C. annuum alleles result in lower genotypic values than C. chinense alleles

^dPercentage of phenotypic variance explained by each QTL

^earcsine(sqrt(x)) of fraction of L₁ larvae that survived to L₂ stage

^farcsine(sqrt(x)) of fraction of L₁ larvae that survived to pre-pupa stage

^gbased on a visual scale: 0 (<50 cm⁻²), 1 (50–100/cm⁻²), 2 (100–200 cm⁻²), and 3 (>200 cm⁻²) at the region near to the veins and midrib on the abaxial leaf surface of fully developed leaves at three different plant stages: early vegetative stage (3 weeks after planting), vegetative stage (6 weeks after planting), and reproduction stage (9 weeks after planting)
