| 摘 要： | 玉米杂种优势的利用为我国玉米产量大幅度提高发挥了决定性作用。杂种优势类群的划分是玉米杂种优势利用的基础,对杂交种组配和自交系改良具有重要的指导意义。在前人研究的基础上,总结了玉米主要杂种优势类群性状表现的特点;结合育种现状,分析了我国玉米杂种优势利用模式的现状及发展趋势。为了适应商业化育种的要求,杂种优势模式将逐渐简化,最终将归结为A×B模式,即Reid×非Reid模式。

| Abstract: | The heterosis utilization of maize plays a decisive role in increasing the yield greatly. The classification of heterotic groups is the basis of heterosis utilization, which has important guiding significance for combination of hybrids and improvement of elite inbred lines. The characteristics of main maize heterotic groups are summarized, the status and development trend of heterosis utilization modes are analyzed. In order to adapt to the requirements of commercial breeding, heterosis modes will be gradually simplified, eventually be come down to A × B mode, namely Reid × non-Reid mode. |
