六个温热玉米群体的人工合成及特征特性

Artificial Synthesis and Characteristics of Six Temperate-tropical Maize Populations

为了拓宽玉米种质基础并保持其优良种性,为玉米种质的扩增、改良和创新奠定基础,以我国广泛应用的Reid和Lancaster玉米种质为材料,采用杂交方法分别导入Tuxpeno和Suwan热带种质,构成了Tuxpeno-Reid C0和Suwan-Lancaster C02个基础群体,对2个基础群体进行半同胞轮回选择形成墨瑞1号和苏兰1号群体,再分别导入其他材料重组后形成墨瑞2号和苏兰2号群体,并对墨瑞2号和苏兰2号群体的特征特性及应用前景进行了简述。

In order to broaden maize germplasm base, maintain their excellent characteristics and lay the foundation for amplification, improvement and innovation of maize germplasm. The author sketched the forming process of Tuxpeno Reid Co and Suwan-Lancaster Co by separately transferring tropical maize Tuxpeno and Suwan germplasm into maize Reid and Lancaster germplasm which were wildly applied in China, conducted half-sib recurrent selection to form Morui 1 and sulan 1 populations, and then transferring other materials to form Morui 2 and Sulan 2 populations. Meanwhile, the characteristics and application prospects of Morui 2 and Sulan 2 populations were reviewed.
