Abstract:

To screen out sugar beet varieties with high salt tolerance, 33 sugar beet seedlings were cultured in nutrient solution and treated with salt stress. The salt tolerance of these germplasm resources at seedling stage was evaluated comprehensively by comparing the root length and plant height of these materials and control seedlings. The results showed that: (1) salt stress had the greatest effect on the root of sugar beet seedlings, the smallest effect on SPAD value, and had the general effect on plant height, fresh weight of plant and fresh weight of shoot. (2) 33 materials were eventually classified into three categories: the first was salt-resistant materials, including 19 materials such as ‘54338’, ‘FLORES’, ‘44581’; the second was salt-sensitive materials, including 6 materials such as ‘52212-1’, ‘2928’and ‘54303’; and the third was salt-resistant materials, including 8 materials such as ‘44176’, ‘28010’ and ‘KUHN1387’. It provided material basis for the research of salt tolerance treatment and salt tolerance breeding of sugar beet in the future.

Key words: sugar beet, water culture, seedling stage, salt tolerance evaluation
