- Abstract:
- Selection of materials,mutagenic methods and doses are very important in mutation breeding.The objectives of this experiment was to discuss the mutation breeding technique of soybean by nitrogen ion beam implantation and 60Co-γ ray radiation.The dried seeds of four soybean varieties were treated by nitrogen ion beam implantation including 4×1016，6×1016和8×1016 N+·cm-2 and 60Co-γ ray irradiation of 100,150 and 200 Gy.The biological effects of two treatments on yield traits and quality of M6 generation were compared under the same planting conditions.The results indicated that compared with control，4×1016 and 6×1016 N·cm-2 increased pods per plant(P<0.05) and yield(P<0.01)of Xindadou 3 significantly;8×1016,6×1016and 100 Gy 60Co-γ irradiation decreased seeds number and weight per plant(P<0.05),100seed weight(P<0.05)and protein content of He99756,respectively.100,150 and 200 Gy 60Co-γ ?irradiation increased fat content(P<0.05)of He99-756;4×1016 and 8×1016 N+·cm-2,100 and 200 Gy 60Co-γ irradiation decreased seeds weight per plant(P<0.05)of Xindadou 8,4×1016,6×1016 N+.cm-2 and 200 Gy 60Co-γ?irradiation increased yield of Xindadou 8 significantly;nitrogen ion beam implantation and 60Co-γ irradiation had no effect on the yield,yield components and quality of Shidadou 2.Thus the objectives of mutation breeding were determined according to sensitivity of materials,mutagenic methods and doses.
