| 摘 要： | 利用不同能量的氮离子注入棉花种子，分析了Ｍ１代的损伤效应及Ｍ２代的诱变效应。结果表明，３０Ｋｅｖ的氮离子Ｍ１代损伤度显著大于２０Ｋｅｖ，Ｍ２代农艺性状变异谱较２０Ｋｅｖ宽，３０Ｋｅｖ变异率是２０Ｋｅｖ的２－４倍，有较好的诱变效果。

| Abstract: | Using N + ion implantation with different energy into dry seeds of cotton,injury effects in M 1 generation and mutagenic effects in M 2 generation were analysed.The results showed that the injury rate of N + ion implantation with 30 Kev energy in M 1 generation was significant greater than that with 20 Kev energy.And its wider variation spectrum of agronomic characters in M 2 generation was demonstrated.The variation rate of the 30 Kev in M 2 was 2 to 4 times of the 20 Kev.A satisfactory mutagenic effect could be obtained by N + ion implantation with 30 Kev energy. |
