摘　　要：辽宁省玉米新品种选育研究在全国占有重要地位。"七五"以来,由辽宁省育种单位育成的丹玉13号、沈单7号、铁单10号等玉米杂交种在生产上迅速推广应用,特别突出的如丹玉13号、沈单7号等优良杂交种已成为国内许多省份的主栽品种。但"八五"、"九五"期间,辽宁省玉米育种曾出现过徘徊不前的局面。从辽宁省"两五"期间审定的玉米品种的遗传基础入手,分析了辽宁省玉米种质基础、杂种优势模式以及辽宁省玉米杂交种选育现状。辽宁省主要的玉米杂种优势模式是Reid×旅大红骨,Lancaster×旅大红骨,外杂选亚群×旅大红骨。The maize breeding in Liaoning province plays very important roles in China. Since the Seventh Five Years' Plan of National Economy Development, the maize hybrid bred in Liaoning province, such as Danyu 13, Shendan 7 and Tiedan10 etc., have extended and used rapidly in maize production, especially the superior hybrid such as Danyu 13 and Shendan 7, have been the main planting varieties in many provinces in China. But in the period of the Eighth and Ninth Five Years' Plan of National Economy Development, the maize breeding had ever developed very slowly. It was analyzed in this article of the maize germplasm foundation and heterosis model and the situation of maize breeding in Liaoning province through the ten years' varieties verified in Liaoning province. The main heterosis model of Liaoning province are Reid×Luda Red Cob, Lancaster×Luda Red Cob and Exotic Hybrid Selected Lines×Luda Red Cob.
