Abstract: To explore the grain-filling characteristics and its quality forming of super-high-yield, grain filling rate and quality characteristics of wheat were analyzed through 17 varieties in test. The results showed that in the early filling stage, the grain filling rate of super-high-yield wheat varieties was lower than the conventional varieties. But the grain filling rate was higher of super-high-yield wheat varieties than the conventional ones within 10 days before maturation, which were 1.74 and 1.15 g·d-1 per thousand grains, respectively. Influences of different years on grain-filling characteristics in wheat were quite different, and there was relevance between wheat yield and flour quality in a certain extent. The farinography mass number of testing super-high-yield and conventional varieties were 99.8 and 99.0 on average.
