对87个试验点的资料分析，绵阳26的主要性状与产量的回归方程为：y=-1084．3321＋5．265x1+9.0142x2＋5.2486x3＋8.3796x4＋6．3627x5。经偏回归和偏相关分析，产量构成因素中，千粒重，有效穗对绵阳26的产量贡献和影响最大（b’4=1．2769．b’2=1．1272，R2y0=0．7287，R4y0=005689）；而千粒重、有效穗、穗粒数之间为负相关，存在着不同程度的制约关系。在本资料现有产量的基础上，稳定千粒重，主攻穗数和穗粒数的提高，是发挥绵阳26高产潜力的决定因素。
The data of 87 experimental sites showed that the regression equation of main characters and yield of Mianyang 26 was: y = -1084.3321 + 5.265x1 + 9.0142x2 + 5.2486x3 + 8.3796x4 + 6.3627x5. By partial regression and partial correlation analysis, among the components of grain yield, grain weight and effective spike contributed most to the yield of Mianyang26 (b’4 = 1.2769.b’2 = 1.1272, R2y0 = 0.7287, R4y0 = 005689). However, there was a negative correlation between 1000-grain weight, effective panicles and grains per spike, with different degrees of restriction. On the basis of the current output of this data, stabilizing the 1000-grain weight, increasing the number of main spikes and grains per spike is the determining factor for the potential of high-yielding in Mianyang 26.
