Description Seedling leaf blade glossiness and trichome density are morphological traits associated with shoot fly resistance (SFR). A fine-mapping population was developed for shoot fly resistance by crossing introgression lines RSG04008-6 (susceptible) × J2614-11 (resistant). A total of 1984 F2 population was genotyped using five SSR markers. This genotyping data can be utilized to identify the recombination events between the flanking markers Xgap001 and Xtxp141 for seedling leaf blade glossiness (gl) and trichome density (Td). The SFR QTLs were mapped to a 37–72 centimorgan (cM) or 45–60 Mb interval on the long arm of sorghum chromosome 10 (SBI-10L) with flanking markers Xgap001 and Xtxp141. One QTL each for glossiness (QGls10) and trichome density (QTd10) were mapped in marker interval Xgap001-Xnhsbm1044 and Xisep0630-Xtxp141.
