| Abstract: |
| Dried foundation seeds of two hot pepper cv.Tiansui Yangjiao and Gannong Xianjiao were sent to receive space mutation treatment on board Shenzhou No.3 spaceship.After coming back,the integrated technology of AFLP technique and additive selection in sunlight greenhouse were used to detect the treatment effect for seeds.Two generations can be selected in use of sunlight greenhouse additive selection technology.First,good mutation was selected.After self fertilization good self-fertilized line was selected.In the same time,detecting cross-mate and selecting good hybrid were conducted.The result showed that obvious mutant happened in first generation for these two hot pepper cultivars.After four-generation self fertilization,most purity self fertilized line were selected out.In use of integrated technology of space mutation,AFLP technique and sunlight greenhouse additive selection,the breeding efficiency was enhanced obviously,and a new hot pepper F1 hybrid Hangjiao No.3,with early maturation,good quality,high yield,stress resistance,wide suitable to environment,had been bred after only three years. |
