Two experiments were carried out to examine the effects of ionizing radiation on protein content of soy beans and to estimate the potential value of ionizing radiation in soy bean breeding. In experiment 1, seed of three cultivars were acutely irradiated by gamma ray doses of 8 krad and 16 krad. Seeds of M3 plants were analysed for protein content by the biuret method. Selection within each variety was made to isolate plants having about 2% higher protein content than the control populations. In the M4 and M5 generations, selected populations were evaluated for the effectiveness of selection in the M3 generation. As a result, it was concluded that selection for protein content in the M3 generation was effective, because selected populations maintained a higher protein content in the M4 and M5 generations. Increases of mean protein contents of selected populations were 2.98 - 3.42%, -0.11 - 1.02% and 0.39 - 1.26% in the M3, M4 generations respectively in comparison with the mean protein content of control populations. In experiment 2, growing plants of soy bean cultivar were irradiated with doses of 2.9 krad and 6.1 krad from germination to maturation in a 60 Co gamma field. Seeds on individual lines in M5, M6 and M7 plants were determined for their protein contents by the Kjeldahl method and the upper 10% of the treated lines were selected for progeny testing. From the results of the anlysis of variance for each trait, significant differences were observed between the control variety and selected lines for all the MenosTwo experiments were carried out to examine the effects of ionizing radiation on protein content of soy beans and to estimate the potential value of ionizing radiation in soy bean breeding.
