摘要

实验结果表明：不同基因型水稻材料Ｍ１代生理损伤，Ｍ２代叶绿素、株高及抽穗期突变频率和诱变效率均存在着较大的差异；Ｍ２代苗期叶绿素缺失突变频率和诱变效率高的材料，其抽穗期、株高突变频率和诱变效率并不一定高；用早熟、半矮秆突变体为母本选育的品种在氮离子注入时不但辐射敏感性差，同时未出现更早熟突变和高秆突变。

Abstract

The biological effects of nitrogen ion implantation on different genotype rice（Oryza sativa L） were studied.The results showed that there were obvious differences in physiological damages for the M1 generation

mutation frequencies and mutagenic efficiencies of chlorophyll

heading date and plant height for M2 generation of different genotypes.Treated by nitrogen ions

the varieties with high mutation frequency and mutagenic efficiency of chlorophyll in the M2 generation were not necessarily high in those of heading date and plant height.Moreover

the radiation sensitivity of Fu8530 and Fuxian No.6 which were bred by using early maturing and semidwarf mutants as maternal plant was low.The early maturing and high stature mutation were not induced with these two varieties.
