本文以21个自交系为材料探索了测定籽粒最大鲜体积Vf的简便方法。提出运用回归分析方法以成熟籽粒干体积Vd推算籽粒最大鲜体积的方法,其简化回归方程Vf=1.32Vd,且求得Vd与Vf间的相关系数为r=0.8981。本文认为这一公式是适用于杂交种的Vf的推算的。
In this paper, 21 inbred lines as material to explore the determination of the maximum fresh volume of grain Vf a simple method. A regression analysis method is proposed to calculate the maximum fresh volume of grain with dry kernel dry matter volume Vd. The simplified regression equation Vf = 1.32Vd, and the correlation coefficient between Vd and Vf is obtained as r = 0.8981. This paper considers that this formula is suitable for the prediction of hybrid Vf.
