Abstract: The seeds of tomato were irradiated by extra-low energy ion-beam .We observed the rate of bud and the property of agronomy in the field. The results indicated the range of the rates of bud was not wide, and took on the graph of "the type of saddle". It was obvious that some individual plants' cotyledon seemed the shape of hook in the colony of young seedling in M0. We discovered some varied plants in M1 under the dosage of 7×1017 N+/cm2 . They had thin-leaves, long-flowers and outstanding variations in the plant and fruit. Furthermore we analyzed the isozyme patterns with the method of gel electrophoresis. The results was that the activity and strips of isozyme of the tomato seedling under several kinds of dosage were different in quantity and color. Therefore, there might be some effects in tomato breeding of irradiation by extra-low energy ion-beam.
