甜菜含糖率与根重关系的研讨

Study on the Relationship between Beet Root Weight and Sugar Content

本文对24个甜菜品系的根重与含糖率相关性进行了研究分析。结果表明：其中22个品系的单株根重与单株含糖率表现为无相关性，2个品系的单株根重与单株含糖率表现为显著负相关；为了进一步研究，我们对24个品系的平均单株含糖率与平均单株根重进行了相关分析；结果为二者无相关。如果这一结论具有广泛性，将对甜菜育种研究起到重要作用。

This paper analysed correlation between root weight and sugar content in 24 sugar beet diploid lines. The results showed that 22 beet lines have no correlations between the root weight of per plant and its sugar content,2 lines gave prominent negative correlation. the further correlation analysis showed the sugar content of even each beet with its root weight has no correlation in 24 beet Lines. The result, being a wide ranging nature, will play a important role in the future sugar beet breeding.
