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 experiment, from the evolution and evolution of population fertility, the natural phenomenon of improved maize hybridization in the early 1960s and early 30s was analyzed in the maize area of Hebei-Shandong-Henan region. The results showed that Yield behavior and anti-plaque behavior of a continuous improvement as the basic way of evolution. The grain weight of the extreme hybrid strains increased by 48.4%, leaf index and reversion rate decreased by 4.3 and 1.2 percentage points respectively. The evolutionary process is defined as four stages of evolution: Ⅰ. Sixties, with the new single 1, white single 4 as the representative; Ⅱ. The early seventies, with a single 105, Dan Yu 6 represented; Ⅲ. From the late seventies to the early eighties, represented by Zheng Dan 2 and Bo Dan 1; Ⅳ. From the early 1980s to the early 1990s, represented by Yantan 14 and Yeda 2. Evolution and Evolution of Maize Hybrid Population Fertility Evolution Follow the biological evolution law of “Multiple Dynamic Metabolic Aggregation Clusters, Systemic Breathing Progressively”.
