DescriptionCS-B18 is an alien chromosome substitution line (2n=52) in which the chromosome 18 pair of G. hirsutum has been replaced by the corresponding chromosomal material from G. barbadense doubled haploid line 3-79 which has high fiber quality and length.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 recurrect backcrossing to G. hirsutum plants monosomic for chromosome-18, 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-B18 were subject to effects of backcrossing and recombination, so >98% of them expectedly derive from G. hirsutum, probably TM-1.
Origin CountryUnited States
Origin DetailTexas, USA
PedigreeTM-1 (G. hirsutum) x 3-79 (G. barbadense), then multiple backcrosses to develop the line CS-B18. Chromosome 18 has been substituted.
