| 摘 要： | 对吉林省3个不同玉米生态产区(乾安县、公主岭市和桦甸市)开展田间试验,将2005~2014年6个玉米品种、3个种植密度所产生的试验数据和Logistic模型相结合,同时加入品种参数以构建产量模型。试验结果表明,所建立的综合多品种的产量模型决定系数达0.8以上,独立样本的模型模拟值和实测值差异不显著(P0.05)。玉米收获指数(HI)与干物质积累内禀生长率(特征参数c)存在线性关系,品种参数v_1~v_2为无单位无量纲线性参数,且v_1介于0.209~0.780,v_2介于-0.036~0.028,v_1~v_2存在较大差异。引入的品种参数是基于多年多点多因素的田间资料,能较好反映不同品种间对干物质积累过程变化的产量响应机制,v_1~v_2可作为品种产量性状的遗传参数。

| Abstract: | The field experiments in three maize ecological regions of Jilin province (Qian'' an, Gongzhuling and Huadian) were studied, the comparative analysis of 6 varieties and 3 planting densities 10 years test data from 2005 to 2014 compared with logistic model, and regarded cultivar genetic parameters as dry matter accumulation in the process of building the most important parameters in the maize yield equation. The result showed that the determination coefficient of established varieties and yield model were above 0.8, the model of independent samples of simulated value and the measured value difference was not significant(P>0.05); maize harvest index and material accumulation process parameters c(material intrinsic growth rate) had linear relationship, the varieties of parameters v1-v2 (dimensionless) as the linear parameters and test species parameters value of v1 between 0.209 and 0.780, v2 between -0.036 and 0.028 which exist larger differences. By the field data of multiple factors, years and places, it can better reflect the different varieties of material accumulation change process of yield response mechanism and v1-v2 can regard as the yield traits of the genetic parameters. |
