摘要: [目的] 为了验证高原地方种质的改良效果,探索其杂种优势类群。[方法] 以国内6个主要杂优模式群的12个代表自交系为母本,5个含高原地方血缘的自交系为父本,按照NCⅡ设计组配60个杂交组合,通过田间种植鉴定,对1的单株产量等11个性状进行配合力分析。[结果] 研究表明,各自交系的所有考察性状均存在显著或极显著的遗传差异。[结论] 81111和8111沃具有较高的一般配合力,地方种质资源的改良取得了较好的效果,瑞德群体、旅大红骨与高原地方种质组配,易获得较强杂种优势。

Abstract: [Objective] In order to verify the plateau local germplasm improvement effect,explore the heterosis groups.[Method] In this study,we employed 12 typical inbred lines from 6 main heterotic pattern groups as female parents and 5 inbred lines which containing local plateau consanguinity as the male parents,designed 60 combinations following the NCⅡ.After field identification,combining ability of F1 was detected by analysis 11 production traits such as yield per plant.[Results] Significant or extremely significant difference were exist in all of these inbred lines within these 11t raits.[Conclusion] The local inbred lines such as 81111,8111 WO show higher general combining ability which means a progress in the improvement of local germplasm resources,and it is easy to gain strong heterosis by combining Reid or Lvdahonggu group with the local plateau germplasm.

Key words: maize, improvement of inbred lines, combining ability, middle latitude high altitude area
