Abstract: In the condition of soil pool, three winter wheat cultivars with different gluten types, Gaomai 8901 (strong), Yumai 49 (medium) and Luomai 1 (weak) were used to investigate the difference of activities of enzymes involved in starch synthesis in the kernel during grain filling. The results indicated that the changes in activities of AGPP, UGPP, SSS, GBSS and SBE of different cultivars all showed a single-peak curve. The peak levels of all tested enzymes in Yumai 49 was higher than those in other two cultivars, and most of the enzymes still maintained higher activities during mid to later grain filling. It suggests that the medium gluten cultivar Yumai 49 had stronger ability in starch synthesis, compared with Gaomai 8901 and Luomai 1.
