Mapping of genes for flower-related traits and QTLs for flowering time in an interspecific population of Gossypium hirsutum × G. darwinii

Description
Summary:Gossypium darwinii possesses favourable genes but are unavailable in cultivated cotton, that are difcult to directly transfer into cultivated cotton by conventional breeding due to interspecic incompatibility. Molecular map will provide the foundation for the genetic dissection of important traits and facilitate utilization in breeding by marker-assisted selection (MAS). However, only one molecular map from a cross between G. hirsutum and G. darwinii has been reported by Chen (2013), while no morphological traits or quantitative trait loci (QTLs) were mapped on it. Here, we produced and reported the rst single sequence repeat (SSR) (PCR-based) genetic backbone-map and mapped genes for ower-related traits (Ya1 on chr A13; R2 on A7; P1 on A5; Lo on D1) and three QTLs for owering time (FT) on chrs D1 and D11, which would greatly enhance the use of G. darwinii-specic desirable genes in future cotton breeding programmes.
