| 摘要: |
| 运用SDS-PAGE和PCR分析了小偃6号及其亲本中高分子质量麦谷蛋白亚基(HMW-GS)组成。结果表明,小偃6号的2个亲本ST2424 /464和小偃96中都存在14和15亚基,而远缘种长穗偃麦草中不存在14和15亚基。从而证明长穗偃麦草并非小偃6号14和15亚基的来源,而ST2424/464和小偃96均有可能是14和15亚基的提供者。通过PCR分析发现了偃麦草中1个不同于普通小麦的麦谷蛋白基因。 |

| Abstract: |
| Through studying HMW-GS composition of Xiaoyan 6 and its parents by SDS-PAGE and PCR, it is found that its two parents ST2424/464 and Xiaoyan 96 have subunits 14 and 15.Although Some researchers believe elongate Elytrigia is the origin of them, this study show it is not a right conclusion.Using PCR,we get a specific fragment of HMW-GS in Elytrgia. |
