Three cotton chromosome substitution lines (CS-B16, CS-B22sh, CS-B25) and TM-1 were crossed with eight strong fiber lines. These 12 parents and their F2 hybrids were grown at Mississippi State in two locations with replicated field plots in 2006. Agronomic and fiber traits were measured and analyzed subject to the general linear model and the additive-dominance genetic model. Parents and F2 hybrids were compared regarding these traits. Variance components were estimated and genetic effects were predicted as well. The detailed genetic information that is useful for fiber and yield improvements will be reported.
