| 摘 要： | 采用2种剂量的C+离子束和2种剂量的Al+离子束处理5个北方夏大豆品种,研究其M2主要农艺性状的遗传变异。结果表明:(1)C+4MeV 8×1012ions/cm2处理的品种冀豆15M2的各农艺性状均明显高于对照;(2)两种离子束4种剂量均使品种楚秀M2的株高降低30%以上,结荚高度降低35%;Al+8×1011ions/cm2处理使品种中黄44M2的结荚高度增加了38.1%;(3)C+4MeV 8×1012ions/cm2与Al+4MeV8×1011ions/cm2处理使各品种M2的单株荚数增加、单株粒数比对照高出50%以上;(4)两种离子束处理对大豆品种百粒重的变异均影响不大。

| Abstract: | Five northern varieties of summer soybean were processed by two doses of C+and two doses Al+ion beam,genetic variation of main agronomic characters were studied in this paper.The results showed that:(1)C+4Mev 8×1012 ions/cm2 processing the M2agronomic traits of JiDou 15were significantly higher than the control;(2)the ion bean processing the M2 plant height and podding height of ChuXiu reduced more than 30% and 35% respsctively;Al+4Mev 8×1011 ions/cm2 processing the M2 podding height of ZhongHuang 44increase 38.1%(3)C+4Mev 8×1012 ions/cm2 and Al+4Mev 8×1011 ions/cm2 processing all M2of the varieties'pod number per plant increased and grain number per plant,were more 50%than the control;(4)Each process has little effect on grain weight of soybean varieties. |
