摘要: 为了给普通小麦的品质改良提供基础材料,利用SDS-PAGE技术对264份阿拉拉特小麦高分子谷蛋白亚基遗传变异进行了分析。结果表明:有5种Ax、5种Ay、4种Gx和3种Gy亚基类型,并形成20种亚基组合类型,其分布频率最高的是Ax1+Ay(A),Gx(A)和Ax1,Gx(A),分别占18.94%和18.18%。在264份材料中,有158份材料(59.85%)中检测到Ay亚基表达,249份材料(94.32%)中检测Gx亚基表达,而Gy亚基仅在部分材料中(20.08%)表达。由此可见,阿拉拉特小麦Glu-A1位点的遗传多样性高于Glu-G1。

Abstract: In order to provide basic materials for the quality improvement, 264 accessions of T. araraticum were analyzed with SDS-PAGE.The results showed that there were 5 Ax, 5 Ay, 4 Gx and 3 Gy subunits, resulting in 20 HMW-GS combinations, among which, combinations Ax1+Ay(A), Gx(A) and Ax1, Gx(A) were the most frequent combinations in T. araraticum, accounting for 18.94% and 18.18%, respectively.Among 264 accessions of T. araraticum, the expressed Ay and Gx subunits were detected in 59.85% and 94.32%, while Gy only observed in 20.08% T. araraticum accessions.These results indicated that the Glu-A1 had higher genetic diversity than the Glu-G1.

Key words: Triticum araraticum, HMW-GS, genetic variation
