甜菜品质性状与经济性状的相关分析

Correlation Analysis of Quality and Economic Characters in Sugarbeet

通过对18个德国KWS系列甜菜品种的田间对比试验测得的钾、钠、a-N 3个品质性状和含糖率、根产量、产糖量3个经济性状进行性状相关分析,得出15个相关系数,结果表明:钾与根产量和产糖量均呈不显著正相关,与含糖率呈不显著负相关;钠与根产量呈极显著正相关,与含糖率呈极显著负相关,与产糖量呈不显著负相关;a-N与根产量和产糖量均呈不显著正相关,与含糖率呈不显著负相关。

The correlation analysis of potassium, sodium and a-N quality traits and sugar content, root yield and sugar yield of 18 German KWS sugarbeet varieties was carried out through field comparative experiments. Fifteen correlation coefficients are obtained. The results show that: There was no significant positive correlation between potassium and root yield and sugar yield. There was no significant negative correlation with sugar content. Sodium was positively correlated with root yield, negatively correlated with sugar content, but not negatively correlated with sugar yield. a-N was not positively correlated with root yield and sugar yield, but negatively correlated with sugar content.
