Summary of QTLs in interspecific cotton (Gossypium hirsutum × G. barbadense) population associated with dry matter yield (DM), seed-cotton yield (SC), harvest index (HI), boll weight (BW), boll number (BN), osmotic potential (OP), carbon isotope ratio (δ13C), canopy temperature (CT), chlorophyll a (Chl-a) and b (Chl-b) contents, and fiber length (FL), length uniformity (FLU), strength (FS), elongation (FE), fineness (FF) and color (FC).
-
↵Number of QTLs at which G. hirsutum (GH) orG. barbadense (GB) are favorable or the heterozygote superior (H+) or inferior (H−) to either homozygote (overdominance or underdominance, respectively).
-
↵Number of QTLs specifically effective under well-watered or water-limited irrigation regime, or that specifically affected relative values (water-limited/well-watered).
