The Gossypium genus contains 5 tetraploid (AD 1 to AD 5, 2n = 4×) and over 45 diploid (2n = 2×) species (where n is the number of chromosomes in the gamete of … Gossypium hirsutum, also known as upland cotton or Mexican cotton, is the most widely planted species of cotton in the world. A dry period is needed for fruit ripening. In 2004 the main producers of Gossypium barbadense were the … The subgenomic origin (A vs. D) of most, and … Interspecific hybrids ensued after crossing G. hirsutum and G. barbadense. In the present report, the pollen from a pentaploid (2n = … Identification of Chromosome Segment Substitution Lines of Gossypium barbadense Introgressed in G. hirsutum and Quantitative Trait Locus Mapping for Fiber Quality and Yield Traits A Detailed RFLP Map of Cotton, Gossypium hirsutum X Gossypium barbadense: Chromosome Organization and Evolution in a Disomic Polyploid Genome ~ Alesia J. Reinisch," Jian-mjn Dong,* Curt L. Brubaker,t David M. Stelly," Jonathan F. Wendelt and Andrew H. Paterson" About 46.2% of nuclear DNA probes detect RFLPs distinguishing Gossypium hirsutum and Gossypium barbadense; and 705 RFLP loci are assembled into 41 linkage groups and 4675 cM. We previously reported the development of a set of Gossypium hirsutum-G. australe alien chromosome addition lines. The cotton genus Gossypium is composed of about 45 diploid and 5 allotetraploid species (Fryxell 1992). We employ a detailed restriction fragment length polymorphism (RFLP) map to investigate chromosome organization and evolution in cotton, a disomic polyploid. About 46.2% of nuclear DNA probes detect RFLPs distinguishing Gossypium hirsutum and Gossypium barbadense; and 705 RFLP loci are assembled into 41 linkage groups and 4675 cM. Stelly DM, Saha A, Raska DA, Jenkins JN, McCarty JC, Gutierrez OA (2005) Registration of 17 germplasm lines of upland cotton (Gossypium hirsutum), each with a different pair of G. barbadense chromosome or chromosome arms substituted for the respective G. hirsutum chromosome or chromosome arms. The primary gene pool for tetraploid cotton species includes Gossypium hirsutum L., as well as the other four 2n = 52 species of Gossypium (G. barbadense, G. mustellinum, G. tomentosum and G. darwinii).To help overcome barriers to effective introgression, we have developed a number of alien chromosome substitution (CS) lines from G. barbadense, G. mustellinum and G. …
