摘　　要：利用并单1号父母本太系3和20-1118两个核心玉米种质选育创新16个玉米自交系,组配审定适宜山西省不同生态区的13个玉米品种,其中累计推广面积在30万hm^(2)以上的玉米品种8个。为了探讨玉米核心种质的改良利用,本文对改良创新种质进行了综合分析与评价,并对玉米循环育种、类群划分与杂优模式等进行探讨,以期为山西省玉米核心种质改良创新提供参考。In this paper,16 maize inbred lines were created by using the two core maize germplasms of Taixi 3 being as parents for Bingdan 1 and 20-1118,and had bred 13 maize varieties suitable for different ecological regions in Shanxi Province.Among them,8 maize varieties were promoted for cumulative area of more than 300000 hm^(2).In order to explore the improvement and utilization of maize core germplasms,this article comprehensively analyzed and evaluated the improved and innovated germplasms,as well as explored maize cycling breeding,group division and heterosis model,etc,so as to provide a reference for the improvement and innovation of maize core germplasms in Shanxi Province.
