the identification of molecular markers linked to leaf curl virus (clcuv) disease resistance in cotton has the potential to improve both the efficiency and the efficacy of selection in cotton breeding programs. genetic analysis suggested that clcuv resistance is controlled by a single dominant gene. in this study, an interspecific f2 population derived from a cross of gossypium barbadense and g...
WHORLED mutant in G. herbaceum has been reported from the Agricultural A Research Station, Surat, Bombay State, India, by CHAVDA and PATEL (1954). It had some phenotypic resemblance to the cluster-short branch mutant reported previously (PATEL, MUNSHI, and PATEL, 1947) the important common characteristic being short one-noded fruiting branches terminating in more than one flower bud. While the ...
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...
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...
