Abstract: By using strong gluten wheat 9356,medium gluten wheat Yangmai158 and weak gluten wheat Ningmai9 as materials,the effects of cultivars and sowing date on the starch viscosity characterics were studied using fast viscosity analyz2 er (RVA). The results indicated that cultivars and sowing date had remarkable effect on the starch viscosity characteristics, there were remarkable interaction effects on final viscosity,setback and pasting temperature.With the delay of sowing dates, peak viscosity,trough viscosity,breakdown and final viscosity setback and peak time were remarkable increased. But there were different in the range. The effect of sowing dates was larger on strong gluten wheat,medium gluten wheat than weak gluten wheat. The correlation analysis showed negative correlation between the peak viscosity,trough viscosity,breakdown,fi2 nal viscosity and the precipitation of seeding to maturation and flowering to maturation,positive relationships between aver2 age temp and the peak viscosity,trough viscosity,breakdown,final viscosity. There were negative correlation between the peak viscosity,trough viscosity,breakdown and the sunshine hours of seeding to maturation and flowering to maturation.
