QTLs Analysis and Validation for Fiber Quality Traits Using Maternal Backcross Population in Upland Cotton
Cotton fiber is renewable natural fiber source for textile. Improving fiber quality is an essential goal for cotton breeding project. In present study, F14 recombinant inbred line (RIL) population was backcrossed by the maternal parent to obtain a backcross (BC) population, derived from one Upland cotton hybrid. Three repetitive field trials were performed by randomized complete block design wi...
متن کاملTwo genomic regions associated with fiber quality traits in Chinese upland cotton under apparent breeding selection
Fiber quality is one of the most important agronomic traits of cotton, and understanding the genetic basis of its target traits will accelerate improvements to cotton fiber quality. In this study, a panel comprising 355 upland cotton accessions was used to perform genome-wide association studies (GWASs) of five fiber quality traits in four environments. A total of 16, 10 and 7 SNPs were associa...
متن کاملGenetic Studies of Fiber Quality Characters in Upland Cotton
Five upland cotton cultivars were crossed in a complete diallel crossing system to investigate inheritance pattern and combining ability of parents for different fiber quality traits like staple length, fiber strength, fineness and uniformity. The study was carried out in the Department of Plant Breeding and Genetics, University of Agriculture, Faisalabad during the years 2005-07. Highly signif...
متن کاملIdentification of QTL for Fiber Quality and Yield Traits Using Two Immortalized Backcross Populations in Upland Cotton
Two immortalized backcross populations (DHBCF1s and JMBCF1s) were developed using a recombinant inbred line (RIL) population crossed with the two parents DH962 and Jimian5 (as the males), respectively. The fiber quality and yield component traits of the two backcross populations were phenotyped at four environments (two locations, two years). One hundred seventy-eight quantitative trait loci (Q...
متن کاملQTL Mapping for Fiber and Yield Traits in Upland Cotton under Multiple Environments
A population of 178 recombinant inbred lines (RILs) was developed using a single seed descendant from a cross between G. hirsutum. acc DH962 and G. hirsutum. cv Jimian5, was used to construct a genetic map and to map QTL for fiber and yield traits. A total of 644 polymorphic loci were used to construct a final genetic map, containing 616 loci and spanning 2016.44 cM, with an average of 3.27 cM ...
