摘　　要：在实验基础上，从群体生育型演变进化角度分析了冀鲁豫夏玉米区六十年代初至九十年代初三十年间玉米杂交种种性提高的自然现象，明确了玉米杂交种群体生育型以产量行为与抗斑一倒行为的持续改良为基本途径演进。极端杂交种株粒重提高了４８．４％，叶斑指数与倒折率分别下降了４．３与１．２个百分点。演进过程界定为四个演化阶段：Ⅰ．六十年代，以新单１、白单４为代表；Ⅱ．七十年代前期，以群单１０５、丹玉６为代表；Ⅲ．七十年代后期至八十年代初，以郑单２、博单１为代表；Ⅳ．八十年代前期至九十年代初，以烟单１４和掖单２为代表。玉米杂交种群体生育型演变进化遵循“多元动态代谢结群，系统吐纳循序渐进”的生物进化规律。Based on the experiments and the plant population growth types development and evolution theory,this paper analyzed the natural phenomenon of the corn hybrid characters improvement during 30 yesrs from early 1960's to early 1990's in Hebei-Shandong-Henan summer corn planting zone.The study indicated the evolution ways of corn hybrid population growth types relied on continuous improvement of the yield,spotted diseases and lodging resistance.During the past 30 years,maximum grain yield of single plant increased 48.4%.The leaf spot index, lodging and stem broken rates reduced 4.3% and 1.2% respectively.The evolution process can be divided into four stages.The four stages and their associated representing corn hybrid are :1.1960's Xindan 1 and Baidan4;2.early 1970's,Qundan 105 and Danyu6;3.late 1970's to the beginning of 1980's, Zhengdan 2 and Bodanl;4.early 1980's to early 1990's,Yandan 14 and Yedan2.The hybrid population growth types evolution followed the organic evolution law,that is 'forming groups by multi-species dynamic metabolization,getting rid of the stale and taking in the fresh,developing in an orderly way and step by step'.
