本文对马铃薯主要数量性状作了选择指数的估算,建立了三种回归方程:1.地上部选择了株高(x_1)、茎粗(x_2)、主茎数(x_3)、分枝数(x_4),其回归方程为 Y=-0.0052x_1+1.0482x_2+0.6305x_3+0.102x_42.地下部选择了块数(x_5)、单块重(x_6),其回归方程为:Y=0.3337x_5+17.5817x_63.地上部和地下部揉合在一起进行估算的回归方程为 Y=-0.0452x_1+2.6844x_2+1.0644x_3+0.2501x_4+0.0498x_5+4.6304x_6
In this paper, the selection index of potato main quantitative traits was estimated, and three regression equations were established: 1. The plant height (x_1), stem diameter (x_2), number of main stems (x_3), number of branches ), And the regression equation is Y = -0.0052x_1 + 1.0482x_2 + 0.6305x_3 + 0.102x_42. The number of blocks (x_5) and the weight of single block (x_6) were selected for the lower part of the ground. The regression equation was Y = 0.3337x_5 + 17.5817x_63 The regression equation estimated by combining the aerial part and the ground part together is Y = -0.0452x_1 + 2.6844x_2 + 1.0644x_3 + 0.2501x_4 + 0.0498x_5 + 4.6304x_6
