A BIL Population Derived from G. hirsutum and G. barbadense Provides a Resource for Cotton Genetics and Breeding
To provide a resource for cotton genetics and breeding, an interspecific hybridization between Gossypium hirsutum cv. Emian22 and G. barbadense acc. 3-79 was made. A population of 54 BILs (backcross inbred lines, BC1F8) was developed with the aim of transferring G. barbadense genes into G. hirsutum in order to genetically analyze these genes' function in a G. hirsutum background and create new ...
متن کاملResistance to Meloidogyne incognita Race 3 and Rotylenchulus reniformis in Wild Accessions of Gossypium hirsutum and G. barbadense from Mexico.
Forty-six accessions of G. hirsutum and two of G. barbadense were examined for resistance to Meloidogyne incognita race 3 and Rotylenchulus reniformis in environmental growth chamber experiments, with the objective of finding new sources of resistance. Only the G. barbadense accessions, TX-1347 and TX-1348, supported significantly less reproduction by R. reniformis than the susceptible control,...
متن کاملEvaluation and Exploration of Favorable QTL Alleles for Salt Stress Related Traits in Cotton Cultivars (G. hirsutum L.).
Soil salinization is one of the major problems in global agricultural production. Cotton is a pioneer crop with regard to salt stress tolerance, and can be used for saline-alkali land improvement. The large-scale detection of salt tolerance traits in cotton accessions, and the identification of elite quantitative trait loci (QTLs)/genes for salt-tolerance have been very important in salt tolera...
متن کاملMolecular Mechanisms of Fiber Differential Development between G. barbadense and G. hirsutum Revealed by Genetical Genomics
Cotton fiber qualities including length, strength and fineness are known to be controlled by genes affecting cell elongation and secondary cell wall (SCW) biosynthesis, but the molecular mechanisms that govern development of fiber traits are largely unknown. Here, we evaluated an interspecific backcrossed population from G. barbadense cv. Hai7124 and G. hirsutum acc. TM-1 for fiber characterist...
متن کاملInheritance and variation of lint yield and fiber traits in a partially introgressed (Gossypiumbarbadense L. × G. hirsutum L.) population of cotton
The objective of this study was to evaluate a partially introgressed (Gossypiumbarbadense L. × G. hirsutum L.) population of cotton for two years. The traits that studied were lint yield per plant, lint %, fiber length, fiber strength and micronaire. A total of 31 cytogenetically stable lines (2n=4x=52) were produced from a cross between a G. barbadense line, Carnak and a G. hirsutumline, 4S,...
