Identification of small effect quantitative trait loci of plant architectural, flowering, and early maturity traits in reciprocal interspecific introgression population in cotton

Cotton is a economically important crop and its production and quality depends on plant fiber and architectural traits. Plant architectural traits are complex traits and controlled by multiple small effect QTLs. We developed a reciprocal introgression population in cotton segregating for only smaller number and size of the introgression segments. This population enabled us to identify multiple small effect QTLs controlling plan architectural traits and early maturity traits in cotton that can be an important resource to understand genetic control of these traits.
