Discussion on Strategies and Technical Ways for Utilization of Introduced Maize Germplasm

玉米品种的换代离不开种质的创新,外来种质是我国玉米自交系选育的重要基础材料。本文分析了近年来引进国外优良新种质的优良特征特性,提出了这批新种质的利用途径和选育成功的技术措施。认为合理利用这批新种质将会进一步提升我国瑞得种质和兰卡斯特种质的竞争力。

Maize introduced germplasm is a valuable resource for developing new inbred lines in China. In this paper,the excellent characteristics of maize germplasm introduced in recent years are generalized,and new technical ways for their utilization were suggested. The competition force of China Reid and Lancaster germplasm will be further promoted by rational utilization of these introduced germplasm in maize breeding.
