摘要: Thirteen chromosome substitution lines (CS-B) with individual 3-79 Gossypium barbadense L. or arms substituted into TM-1, G. hirsutum L., were crossed fi ve Upland cultivars and additive dominance effects for ber micronaire, elongation, length, strength measured over four environments. Additive genetic considerably larger than environmental interaction effects. Fiber of FM966 282 240 kN m kg −1 , respectively. had greater length (1.13 mm) (12.90 ) any CS-B line; however, CS-B25 the greatest (8.97 among lines. The negative effect was −1.29 mm (CS-B22sh). Although several on strength, none more TM-1 (−5.31 ). CS-B02 2.36 8.97 . SG747 (−12.13 CSB07 CS-B18 but signifi cant positive FM966. When elite benefi cial alleles properties uncovered specifi c chromosomes that should aid introgression from Upland.
