摘要

为了引入陆地棉优良基因型中的纤维品质基因，尝试了Suraj (G. Hirsutum)与Suvin (G. Barbadense)的种间杂交。201bc144 19个子代的单株选择结果表明，除铃数外，其余产量组成部分的渗渗系平均值均高于亲本。发芽率(40.9 ~ 47.2%)、铃重(2.5 ~ 8.4g)和纤维强度(21.6 ~ 31.2 g/tex)均有遗传改良。bc14f4后代SPS 32-94、SPS 33-94、SPS 39-94、SPS 45-31、SPS 46-31、SPS 48-31、SPS 49-31和SPS 50-31具有较好的棉花育种应用前景。

Evaluation of breeding potential of introgression lines developed from inter-specific crossing between upland cotton (Gossypium hirsutum) and Gossypium barbadense

Interspecific crosses were attempted between Suraj (G. Hirsutum) and Suvin (G. Barbadense) in order to introgress fibre quality genes in elite genotypes of upland cotton. The results of 201BC1F4 individual single plant selections of 19 progenies indicated that the average values of introgression lines for all the yield components except boll number had higher values than the parental gentotypes. The ginning percentage (40.9-47.2%), boll weight (2.5-8.4g) and fibre strength (21.6-31.2 g/tex) indicated genetic improvement of the traits. BC1F4 progenies SPS 32-94, SPS 33-94, SPS 39-94, SPS 45-31, SPS 46-31, SPS 48-31, SPS 49-31 and SPS 50-31 were found to be promising for use in cotton breeding programme.
