Genetic effects of thirteen Gossypium barbadense L. chromosome substitution lines in topcrosses with upland cotton cultivars: I. Yield and yield components.

From: Crop Science | Date: May 1, 2006| Author: | Copyright information

Gossypium barbadense L. line 3-79 is lower in yield, has smaller bolls and longer, finer, and stronger fibers than upland cotton G. hirsutum L. Thirteen chromosome substitution (CS-B) lines with individual 3-79 chromosomes or arms substituted into TM-1, G. hirsutum, were top crossed with five elite cultivars and additive and dominance effects for the yield components, lint percentage, boll weight, seed cotton yield, and lint yield, were measured over four environments. Additive effects were greater than dominance effects for all traits. CS-B lines had smaller additive and homozygous ...
