用６０Ｃｏγ射线对１７个野生稻种共５３份材料和栽培稻８个地方品种的种子进行３种剂量的辐照处理。结果表明，种子发芽率和成株率与不辐照种子相比有变异，且变异大小与辐照的剂量有关；Ｍ２代出现的突变以普通野生稻、古巴多年生野生稻和栽培稻较多，其余野生稻种未发现突变株。突变体中以株高、抽穗期的变化较大，以３．５万ｒａｄ、３６１ｒａｄ／ｍｉｎ处理的突变率较高，２．５万ｒａｄ、２０９ｒａｄ／ｍｉｎ处理的突变率较低，４．５万ｒａｄ、４５２ｒａｄ／ｍｉｎ处理因辐照剂量大，多数材料未能成苗。野生稻经辐照诱变后有栽培化倾向
Fifty-three materials from 17 wild rice species and 8 cultivated rice varieties were irradiated with 60Co γ-rays. The results showed that the seed germination rate and the adult plant rate were different from those of the non-irradiated seed, and the variation was related to the dose of irradiation. The mutation occurred in the M2 generation was more than the wild and the perennial wild and cultivated rice, The remaining wild rice species did not find mutants. The mutation rate of plant height and heading stage was large, and the mutation rate was high at 35,000 rad and 361 rad / min. The mutation rate at 25,000 rad and 209 rad / min was lower. 4.5 Thousands of rad, 452rad / min treatment due to radiation dose, the majority of materials failed to seedlings. Wild rice after irradiation mutagenic tendencies
