【摘要】 以基因枪法转化获得的转bar基因水稻"HR"为供体亲本,两系法亚种间杂交稻优势组合"65396"的恢复系"E32"为受体亲本,经过4次回交转育成对除草剂Basta具有稳定抗性的水稻新品系"E32HR"。对"E32HR"及其杂种"培矮64S/E32HR"的主要农艺性状进行比较分析的结果表明,除了"E32HR"的株高明显高于"E32"以外,其余性状均无明显差异。文中对转基因育种与常规育种的结合以及抗除草剂水稻的利用等问题进行了讨论。更多还原

【Abstract】 A new rice variety "E32HR" which was resistant to herbicide "Basta" was bred by transferring gene bar from the donor, a genetically modified organism "HR" obtained by biolistic method, into the breeding line "E32", a restorer of the super hybrid rice "65396" (Peiai 64S/E32) through successive backcrossing for four times. Comparative test result showed that there was no significant difference between "E32HR" and "E32","Peiai 64S/E32HR" and "65396" in main agronomic traits, except that the plant height of "E32HR" was significantly higher than that of "E32". The combination of transgenic breeding and traditional breeding as well as the utilization of herbicide resistant rice varieties were discussed.更多还原
