MUTAGENtC EFFECTS OF JOINT TREATMENT WITH γ-RAY AND CHEMICAL MUTAGENS ON SOYBEAN |
| |
| Abstract: | Studies on mutations induced by γ-ray combined with chemical muta-gen treatment on soybean seeds were carried out. In M1 generation, physiological damages were obvious. Different types of deformed plant appeared. The course of growth and development were delayed. In M2 generation, the mutations on qualitative and quantitative characters were expressed.The mutation frequency was 3.29%.A mutant with seed weight of 8g per 100 seeds higher than original variety was obtained. The effect of joint treatment with physical and chemical agents is more mutagenic than that of single treatment. Therefore, it is an effective method in enhancing the mutagenic frequency. |
