- Abstract:
- ?Superior to conventional irradiation source,heavy ion beam is a new technique in plant mutation breeding,which has been applied in wheat,potato and vegetable.However,little information is available in soybean.Emergence rate,variation in growth and development performance,survival rate as well as single seed size in the first mutation progeny were examined by eleven released cultivars treated with six irradiation dosages.Delayed emergence,crippled cotyledon leaf,yellow and weak seedlings were observed.With the processes of development,more plants died off and thus fewer plants left at maturity.150 Gy increased seed size while superhigher irradiation dosage was not effective in producing large population and thus mutation selection.100 Gy was advised for extensive use of heavy ion irradiation in soybean mutation breeding.
