摘要
通过对玉米穗部性状整齐度与产量的相关分析 ,结果表明 :行粒数整齐度与产量的相关达到极显著 ,回归方程为 :y =- 6 5 0 + 1 0 2x ;穗行数整齐度与产量的相关达显著 ,回归方程为 :y =1 5 6 + 0 5 3x ;
Correlation was analyzed between the uniformity of the corn ears and the corn yield.Result showed that the uniformity of the grain number of the single rows was significantly (at 0 01 level) correlated with the yield.Their regressive formula was y=-6 50+1 02x .The uniformity of the row number of the single ears was significantly(at 0 05 level) correlated with the yield.Their regressive formula was y=1 56+0 53x .While correlation between the ear length uniformity and the yield was not significant.
