摘要/Abstract

摘要： 小麦种子经30kRγ射线照射后,再从M1株取未成熟胚培养,用再生株当代(M2R1)的死苗率、不育株率、结实率及株高变化所反映的损伤程度与对照株（R1）比较，无明显差异；M3R2代的变异率也与对照R2相仿。5天龄幼胚用0.5kR照射处理后的再生株M1R1的损伤程度与对照相仿；M2R2的变异率随不同基因型而有增减，但变异率仍有显著提高。未

Abstract: The M2R1 regenerated plants derived from the immature embryo cultures of the M1 plants from the dry seeds irradiated with gamma rays at 30kR before sowing showed some physiological damage similar to the counterpart R1 plants, while M3R2 failed to increase variation frequency as compared to the contr
