本文首次对小麦旗叶姿态进行了比较系统的细胞遗传学研究。单体、端体的F_1及F_2分析表明:中国春2D染色体上至少有两个旗叶下披基因,即位于2DL上的P_1和2DS上的P_2,前者表达能力很强,后者则较弱,与小偃6号旗叶直立基因共存时分别表现为显性和隐性;小偃6号的旗叶直立基因E也位于2D染色体上,同(P_1+P_2)共存时表现为隐性,仅与P_2共存时则表现为显性。文章还就这些基因的染色体操作等进行了讨论。
This article for the first time a wheat leaf flag gesture more systematic cytogenetic studies. F_1 and F_2 analysis of monomer and terminal body showed that there were at least two flag leaf Phi genes on chromosome 2D in China, that is, P_1 on 2DL and P_2 on 2DS, the former had strong expression ability and the latter was weak , And Xiaoyan 6 flag leaf erected genes showed dominant and recessive, respectively; Xiaoyan 6 flag leaf erection gene E is also located on the 2D chromosome, with (P_1 + P_2) coexist when the performance of recessive, Only with P_2 coexistence is dominant. The article also discusses the chromosomal manipulation of these genes.
