| dc.description.abstract | Molecular markers can be used to stack fiber quality alleles among recombinant inbred lines and thus, aid in the development of unique genotypes. The objective of this study was to determine the potential for stacking Gossypium barbadense (Pima S-6) quantitative trait loci (QTLs) for upper half mean (UHM) fiber length in a G. hirsutum (Tamcot 2111) background through marker-assisted selection. Near isogenic lines that contained unique combinations of 0, 1, and 2 homozygous QTLs for upper half mean fiber length were grown under greenhouse culture at College Station, TX during 2001 and 2002. Genotypes containing a combination of QTLs pAR077a and A1580 increased UHM fiber length above the original recurrent genotype, Tamcot 2111, used to develop the families. Two other stacked combinations failed to increase UHM fiber length above the recurrent parent, Tamcot 2111. Differences in micronaire, fiber bundle strength, uniformity index, and elongation also existed among genotypes, some of which could be explained by the QTLs selected for in each family. The techniques and results in this study suggest that marker-assisted selection is possible and practical in upland cotton. | en |
