摘要
“PN78599群×塘四平头群”是黄淮海夏玉米区主要杂优模式之一,山东省农业科学院玉米研究所围绕“PN78599群×塘四平头群”杂优模式连续改良,选育出鲁单981、鲁单9088等一批玉米新品种,并扩大了该玉米杂优模式的利用群体。本文分析阐述了“PN78599群×塘四平头群”杂优模式的特点、改良成果,并就其利用中存在问题及改良方向进行了研究展望。
“PN78599 Group×Tangsipingtou Group”is one of the main hybrid models in the Huanghe-Huaihe-Haihe summer maize area.The Maize Research Institute of Shandong Academy of Agricultural Sciences has continuously improved this hybrid model and selected a number of new maize varieties such as Ludan 981 and Ludan 9088.The utilization group of the“PN78599 Group×Tangsipingtou Group”hybrid model had also been expanded.In this paper,the characteristics,achievements and present problems of this hybrid model were summerized,and then its improvement direction was prospected.
