Description	CS-B22Lo is an alien chromosome substitution line (2n=52) in which chromosome arm 22Lo of G. hirsutum has been replaced by the corresponding chromosomal material from G. barbadense doubled-haploid line 3-79, which has high fiber quality and length. For the opposing arm and all other chromosomes, line CS-B22Lo is expected to be nearly isogenic to G. hirsutum inbred line TM-1. The chromosome substitution line was developed via recurrent backcrossing to G. hirsutum plants monotelodisomic for Te22sh, coupled with recovery of the corresponding monotelodisomic backcross progeny at each generation. The alien chromosome arm is expectedly an intact derivative of most or all the 3-79 chromosome arm, because homologous recombination with the corresponding G. hirsutum chromosome segment was selectively precluded absence of the latter in all BCnF1 plants (monotelodisomic). Greater than 98% of loci on the telosome and the other 25 chromosome pairs expectedly derive from G. hirsutum TM-1, because they were disomic during backcross generations and thus subject to effects of backcrossing and recombination.
