Fig. 2. Estimated location of rice quantitative trait loci (QTLs) affecting sheath blight (SB) resistance, plant height, and heading date identified from present analysis of recombinant inbred lines (RILs) derived from ‘Lemont’ and ‘Teqing’ and comparatively mapped with SB-QTLs from two prior studies involving F₂ and/or F₃ progeny (Li et al., 1995a; Zou et al., 2000). The shaded boxes cover the region where the QTLs are most likely located based on where the likelihood score was within 1 LOD of its maximal value.
