Hybrid Vigour in Interspecific F1 Hybrids of Gossypium hirsutum X Gossypium barbadense for Some Economic Characters

Transformation of Gossypium hirsutum and Gossypium barbadense by Rhizobium rhizogenes: Hairy root induction and gossypol production

Gene Flow between Gossypium hirsutum L. and Gossypium barbadense L. is Asymmetric

As both Pima cotton (Gossypium barbadense L.) and Acala (Upland; G. hirsutum L.) are grown in the southwestern United States, understanding gene fl ow within and among these species is important to maintain genetic purity. In small scale and commercial fi elds, gene fl ow decreased exponentially from 1.44% at 1 m to less than 0.50% at 10 m in Acala cotton. Corresponding values for Pima cotton w...

A detailed RFLP map of cotton, Gossypium hirsutum x Gossypium barbadense: chromosome organization and evolution in a disomic polyploid genome.

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. The subgenomic origin (A vs. D) of most, and chromosomal identit...

Genetic and phenotypic effects of chromosome segments introgressed from Gossypium barbadense into Gossypium hirsutum

MBI9915 is an introgression cotton line with excellent fiber quality. It was obtained by advanced backcrossing and continuous inbreeding from an interspecific cross between the upland cotton (Gossypium hirsutum) cultivar CCRI36 as the recurrent parent and the sea island cotton (G. barbadense) cultivar Hai1, as the donor parent. To study the genetic effects of the introgressed chromosome segment...

Reproductive abnormalities in interspecific crosses involving Gossypium hirsutum and Gossypium arboreum

A successful cross fertilization involving two different species implies that a chain of reproductive process takes place unhampered after pollination. The coordination and interaction between genes or gene complexes in the pollen parent and matching gene or gene complexes in the pistil parent should be hormonious. Understanding of pollen tube growth and pollen attrition is revealed from the st...
