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...
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 کاملEvaluation of Cotton Leaf Curl Virus Resistance in BC1, BC2, and BC3 Progenies from an Interspecific Cross between Gossypium arboreum and Gossypium hirsutum
Cotton leaf curl virus disease (CLCuD) is an important constraint to cotton production. The resistance of G. arboreum to this devastating disease is well documented. In the present investigation, we explored the possibility of transferring genes for resistance to CLCuD from G. arboreum (2n = 26) cv 15-Mollisoni into G. hirsutum (2n = 52) cv CRSM-38 through conventional breeding. We investigated...
متن کاملIntrogression of cotton leaf curl virus-resistant genes from Asiatic cotton (Gossypium arboreum) into upland cotton (G. hirsutum).
Cotton is under the constant threat of leaf curl virus, which is a major constraint for successful production of cotton in the Pakistan. A total of 3338 cotton genotypes belonging to different research stations were screened, but none were found to be resistant against the Burewala strain of cotton leaf curl virus (CLCuV). We explored the possibility of transferring virus-resistant genes f...
متن کاملThe Cytogenetics of Speciation in Asiatic Cotton.
HE cultivated cottons are divided into two groups: the diploid Asiatic species Gossypium arboreum and G. herbaceum and the New World amphidiploids G. hirsutum and G. barbadense. The taxa within each of these groups are readily crossed, and the F, in each case is vigorous and fertile. F, and subsequent generations, however, contain either depauperate types or plants that closely resemble one of ...
