Analysis of [Gossypium capitis-viridis × (G.hirsutum × G.australe)2] Trispecific Hybrid and Selected Characteristics
Speciation is always a contentious and challenging issue following with the presence of gene flow. In Gossypium, there are many valuable resources and wild diploid cotton especially C and B genome species possess some excellent traits which cultivated cotton always lacks. In order to explore character transferring rule from wild cotton to upland tetraploid cotton, the [G. capitis-viridis × (G. ...
متن کاملUpland Cotton (Gossypium hirsutum L.) x Hawaiian Cotton (G. tomentosum Nutt. Ex. Seem.) F1 Hybrid Hypoaneuploid Chromosome Substitution Series
Interspecific germplasm introgression enables unique opportunities for genetic analysis and improvement of domesticated plants, but is commonly impeded by barriers to transmission and recombination, insufficient genetic resolution, and the difficulty of deriving economically suitable products. Such impediments are mitigated to varying extents by the breeding of chromosome substitution lines; ho...
متن کاملIntrogression of resistance to reniform nematode (Rotylenchulus reniformis) into upland cotton (Gossypium hirsutum) from Gossypium arboreum and a G. hirsutum/Gossypium aridum bridging line
Gossypium hirsutum L. is the predominant cotton of commerce and all cultivars of this species are susceptible to the reniform nematode, Rotylenchulus reniformis. To introgress resistance to R. reniformis into the tetraploid 2(AD1) G. hirsutum, a resistant diploid A2-genome Gossypium arboreum accession (A2190) was crossed with a hexaploid 2((AD1)D4) bridging line (G 371) to obtain a tetraploid t...
متن کاملCYTOGENETIC STUDY OF GAMMA IRRADIATED LINES OF COTTON (GOSSYPIUM HIRSUTUM L.)
A cytogenetic study was performed on M4 generation of gamma irradiated lines of Shirpan cultivar of tetraploid cotton (Gossypium hirsutum L.). A significant difference was observed in cytogenetical characteristics such as the number and type of quadrivalents as well as percentage of cells showing abnormality among the irradiated and non irradiated lines. Cytomixis and post- pachytene diffuse st...
متن کاملCytogenetic distinctiveness of sixty-six tetraploid cotton (Gossypium hirsutum L.) cultivars based on meiotic data
Acytogenetic study was performed on 66 tetraploid cotton cultivars (Gossypium hirsutum L.) and their hybrids. The cultivars studied differed significantly in their chiasma frequency and distribution as well as chromosome pairing indicating their genetic differences. Adjacent and alternate quadrivalents were formed in most of the cultivars. A-A or D-D heterozygote translocations occurred in most...
