自330亚群种质在我国玉米育种和生产中的应用

Application of Zi 330 Subgroup Germplasm in Chinese Maize Breeding and Production

分析了2 0世纪70年代至今,自330亚群种质在我国玉米育种和生产中的研究与应用,结果表明,优良玉米自交系自330、oh4 3、4 46、2 0 0B、3H - 2、黄C等,玉米杂交种中单2号、京杂6号、77×自330 (七三单交等)、丹玉6号、铁单4号、四单16、桂顶1号、农大10 8等,在我国玉米育种研究和生产中发挥了重要的作用。其间利用的主要杂优模式为自330亚群与Lan群Mo17亚群、旅大红骨群、改良Reid群和其他综合种选亚群等。

Analysis on the research and application of Zi 330 subgroup germplasm in Chinese maize breeding and production since 1970S of 20th. Indicates that the elite maize hybred lines such as Zi 330,oh 43,446,200B,3H-2,Huang C and elite maize hybrids such as Zhongdan 2,Jingza 6,77×Zi 330,Danyu 6,Tiedan 4, Sidan 16,Guiding 1 and Nongda 108 play a very important role in Chinese maize breeding and production. During this period, the main heterosis patterns are Zi 330 subgroup crossing with Lan group Mo17 subgroup,Lüda Red Cob group,improved Reid group and other subpopulations selected from synthetic varieties.
