特早熟显性无腺体陆地棉转育研究初报

Selection on the Backcross of Early-maturing Dorminant GI andl ess Cotton (G Hirsutum)

从1986年开始,经过7年9代的回交转育,将海岛棉海1的显性无腺体基因转育到特早熟陆地棉品种上来,现已得到一批低酚性状稳定、品质优良、产量与目前推广品种相当的显性无腺体陆地棉品系,为棉花杂优利用和棉子蛋白的综合开发提供了条件。

Since 1986, through nine generations backcrossing in seven years, the gene of dorminant glandless line of Hai 1 (G. batadense)was transfered into early-maturing cultivars of G. Hirsutum. It has been selected a series of lines with dorminant glandless in G. Hirsutum, which are low-phenol, good quality and the yields similar to those extensively used in present culture. It is very useful in utilizing heterosis in cotton and developing the proteins in cotton seeds.
