摘要:

为建立籼稻明恢86再生体系,本研究以明恢86的成熟种子为材料,设置5种不同质量浓度的激素培养基,进行愈伤组织的诱导与增殖。结果表明,籼稻明恢86在组合C[1.0 mg·L-1 6-卞氨基嘌呤(6-BA)2.5 mg·L-1+2,4-二氯苯氧乙酸(2,4-D)]中愈伤组织诱导率最高,达92.3%,说明组合C是诱导明恢86愈伤组织的最佳组合。在此基础上,设置6个草甘膦质量浓度(0、100、200、300、400和500 mg·L-1)的培养基进行愈伤组织的草甘膦抗性筛选,当草甘膦的质量浓度为300~400 mg·L-1时,筛选效果最好,再设置3个质量浓度(300、350、400 mg·L-1),得到临界质量浓度为300 mg·L-1。本研究筛选出籼稻明恢86诱导愈伤组织和增殖的最佳激素组合,为抗草甘膦水稻的开发提供了技术支撑。

Abstract:

To establish the regeneration system of indica rice Minghui 86,the mature seeds of Minghui 86 were used as materials,and five different mass concentrations of hormone culture media were designed for callus induction and proliferation. The callus induction rate of indica rice Minghui 86 in combination C [1.0 mg·L-1 6-benzyladenine (6-BA)+2.5 mg·L-1 2,4-dichlorophenoxyacetic acid (2,4-D)] was the highest,reaching 92.3%,indicating that combination C was the best for callus induction of Minghui 86. On this basis,the callus of indica rice Minghui 86 was selected and six mass concentrations of glyphosate(0,100,200,300,400 and 500 mg·L-1)were set up to screen the glyphosate resistance of callus. When the mass concentration of glyphosate was in the range of 300-400 mg·L-1,the screening effect was best. Three more concentrations(300,350 and 400 mg·L-1)were set,and the critical concentration was 300 mg·L-1. The optimal hormone combination for callus induction and proliferation of indica rice Minghui 86 was found,which provided technical support for the development of glyphosate-resistant rice.

Key words: indica rice Minghui 86, callus, regeneration system, glyphosate
