Description	CS-B02 is an alien chromosome substitution line (2n=52) in which the chromosome 02 pair of G. hirsutum has been replaced by the corresponding chromosomal material from G. barbadense doubled haploid line 3-79 which has high fiber quality and length. In other regards, it is nearly isogenic to G. hirsutum inbred line TM-1. The chromosome substitution line was developed via recurrent backcrossing to G. hirsutum plants monosomic for chromosome-02, coupled with recovery of the corresponding monosomic backcross progeny. The alien chromosome is expectedly an intact derivative of the 3-79 chromosome, because homologous recombination with the corresponding G. hirsutum chromosome (absent) was precluded by the monosomy of all BCnF1 plants. Loci on the other 25 chromosome pairs of CS-B02 were subject to effects of backcrossing and recombination, so >98% of them expectedly derive from G. hirsutum, probably TM-1.
Origin Country	United States
Origin Detail	United States, Texas
Pedigree	TM-1 (G. hirsutum) x 3-79 (G. barbadense), then multiple backcrosses to develop the line CS-B02. Chromosome 02 has been substituted.
