Summary of six component maps used to construct the cotton HDC map.

1)all female and recurrent parents belong to G. hirsutum, and all male parents belong to G. barbadense.2)T3, GV, TH and E3 maps were constructed using JoinMap program. PK and CH maps were constructed using MapMaker program.3)including target region amplification polymorphism (TRAP), sequence-related amplified polymorphism (SRAP), isozyme, gene-derived, and morphological markers.4)the loci not present in any one of the other five maps.5)TRAP, SRAP, morphological and some AFLP markers could not be easily traced back to their description, and were not included in consensus map integration.6)a consensus map constructed with JoinMap (combine data for map integration) using 75 BC1 and 140 RIL populations.
