By means of dropping GA3(50 ppm) and NAA (40 ppm) on the hybrid boll-embryo culturein vitro, one F1 plant ofG. hirsutum × G. bickii was obtained; when F1 branches were grafted on upland cotton and then back-crossed with upland cotton under short-day and cooler-night condition, some BC1 seeds could be harvested. The characteristic segregation was very violent in early generation. Through 3 times of back-crossing and selecting, ten stable hybrid lines with the character of both male parent (viz. red petal-purple spot and strong fibre) and female parent (plant type, earliness, white fibre, lint length, etc.) were established. These lines were assigned as HB red flower lines (HBRL). Transference of character ofG. bickii to upland cotton was proved to be successful for the first time. These new germplasms may play an important role in both the genetic research and new cotton variety breeding.
