Sugar is a product that is consumed more or less anywhere in the world. Sugar, derived from the raw material of two distinct plants- sugar beet and sugar cane, is produced in a wide range of climatic conditions. In sugar beet, a negative correlation was most often reported between root weight and sugar content. To test and update this hypothesis, we have evaluated 7455 single sugar beet roots harvested in a period of 2015–2019 belonging to full-sib, half-sib, O-type and male-sterile lines for root weight, sugar content, and extraction coefficient of sugar. For all tested roots belong to the mentioned families, a positive weak correlation (r = 0.46, P < 0.01) was found between extraction coefficient of sugar and sugar content. A negative weak correlation (r = − 0.2, P < 0.01) was found between root weight and sucrose content which indicates that the negative relationship remains even in new varieties though not as tightly correlated as it was earlier.
