Fig. 2. Genetic linkage map for the BAT 881 x G 21212 population, showing linkage groups that contained significant QTLs for Thrips palmi resistance. The QTLs were identified by single interval mapping (black boxes, D99B = damage 1999B, RA99B = reproductive adaptation 1999B), by joint interval mapping for resistance traits within the same season (gray boxes, J99B = joint for damage and RA in 1999B) and by joint interval mapping for each resistance trait across three seasons (white boxes, JD3s = joint for damage across three seasons, JRA3s = joint for RA across three seasons). The LOD peaks are indicated by black horizontal bars, and their values are shown below the QTL box. Linkage group identification is according to Freyre et al. (1998) and Blair et al. (2003). The cumulative distance, in centimorgans, is shown relative to the topmost marker. Marker loci with a significant distorted segregation are marked by a black triangle.
