Present investigation was carried out to find the QTLs associated with leaf pubescence, jassid resistance and yield traits in cotton. Available SNP based linkage map was used for QTL analysis. Single marker analysis and simple interval mapping identified 24 and 11 associated QTLs, respectively. Composite interval mapping detected only seven QTLs, of which five were associated with jassid injury resistance and leaf pubesence with 8.83–11.64% phenotypic variance explained. One QTL each for seed cotton yield and boll weight was detected. These identified QTLs and markers may be used in molecular breeding for improving yield and insect resistance in cotton.
