摘要: 为从小麦近缘植物长穗偃麦草中寻找氮高效基因,在高、低氮2个水平下,以中国春-长穗偃麦草二体异附加系和二体异代换系为试材,对其氮素利用特性进行了鉴定和遗传分析。结果表明:5E附加系氮素生理利用效率在低氮处理下极显著高于对照中国春,5E代换系氮素生理利用效率在高氮处理下显著高于对照中国春,4E代换系氮素总累积量和籽粒氮累积量在高、低氮处理下均显著高于对照中国春,表明5E和4E染色体可能分别携有促进氮素生理利用效率和促进氮素吸收转运的高效基因,长穗偃麦草5E和4E染色体可以作为提高小麦氮营养特性的有益基因资源。

关键词: 长穗偃麦草, 二体异代换系, 二体异附加系, 氮效率

Abstract: The nitrogen(N) use efficiency was studied with one set of the disomic substitution lines and disomic addition lines of Triticum aestivum L.cv.Chinese Spring(CS)-Agropyron elongatum (Host) under high and low N levels.The 5E genomes of Agropyron elongatum might confer high N physiological efficiency genes because the substitution and addition lines of 5E achieved remarkable higher N physiological efficiency values than Chinese Spring in low and high N treatment, respectively.The 4E genomes of Agropyron elongatum might confer high N absorption and transfer efficient genes because the substitution line of 4E achieved significantly higher values of total N accumulation and grain N content than Chinese Spring in high and low N treatments.Therefore, the chromosomes of 5E and 4E of Agropyron elongatum would be useful genetic resources to improve wheat N efficient features.

Key words: Agropyron elongatum, Disomic substitution, Disomic addition, Nitrogen use efficiency
