A complete set of monosomic alien addition lines developed from Gossypium anomalum in a Gossypium hirsutum background: genotypic and phenotypic characterization.

ABSTRACT: Gossypium anomalum (B₁B₁) is a valuable wild resource for the genetic improvement of G. hirsutum (A₁A₁D₁D₁) in terms of fiber quality and disease and pest resistance, but the inherent difficulties in distant hybridization hinder its utilization in breeding programs. Monosomic alien addition lines (MAALs) are powerful tools for interspecific gene transfer. First, to access useful genes from G. anomalum, a fertile hexaploid from G. hirsutum × G. anomalum was obtained and then additional chromosomes were selected using SSR markers in successive backcrosses and self-crossing from BC₂F₁ to BC₄F₄. Finally, a complete set of 13 MAALs were developed. All
