利用60Co－r射线对3个小豆品种的干种子加以辐照处理，其剂量分别为0（CK）、100、200、300、400、500、700Gy，研究了不同辐射剂量处理M1、M2代5个农艺性状的诱变参数．结果表明：（1）M1代农艺性状均有不同程度受抑制，其平均数与辐照剂量呈负相关，且M1的变异是多方向的，对剂量的敏感程度也因品种、性状而异；辐照处理致变力（h12）京农2号在400～500Gy剂量处理下综合5个性状为最大，而冀红四号在200Gy剂量处理下综合5个性状为最大．（2）M2代株高、主茎节数、单株荚数的平均数在400Gy处理时均比对照显著增高，从变异系数的大小来看，M2变异范围较大的剂量株高为400～500Gy、单株美数为300～400Gy、荚长为400～700Gy和单荚粒数为300Gy左右．（3）诱导变异遗传力（h22）反映了通过辐射诱变获得的遗传变异方差占总方差的比率，单株荚数在辐射剂量为300～400Gy、株高在400Gy时的h22、GS、RGS较大．
The dry seeds of three adzuki bean varieties were irradiated by 60Co-r radiation, and the doses were 0 (CK), 100,200,300,400,500,700Gy, respectively. The effects of different doses of radiation on M1 and M2 generations were studied Mutagenic parameters of agronomic traits. The results showed that: (1) The agronomic traits in M1 were all inhibited to varying degrees, the average number was negatively correlated with the irradiation dose, and the variation of M1 was multidirectional, and the sensitivity to dosage varied with varieties and traits; Irradiation induced mutagenicity (h12) Jingnong 2 under the treatment of 400 ~ 500Gy dose comprehensive five traits maximum, and Jihong four under the 200Gy dose comprehensive treatment of five traits is the largest. (2) The average of plant height, main stem number and pods per plant in M2 was significantly higher than that in control at 400 Gy treatment. From the point of the coefficient of variation, the plant height with M2 variation ranged from 400 ~ 500Gy, the number of single plant is 300-400Gy, the length of pod is 400-700Gy and the number of single pods is about 300Gy. (3) Induced variation heritability (h22) reflects the ratio of variance of variance to total variance obtained by radiation mutagenesis. The number of pod per plant at the dose of 300-400 Gy and the plant height at 400 Gy of h22, GS, RGS Larger.
