A field experiment was conducted using 36 cross combinations of two-line japonica hybrid rice and 4 conventional japonica rice varieties in Northern China, the RVA profile characteristics, amylose content, protein content and eating value of rice were measured, and the correlation of which were analyzed. The results showed that there existed significant correlation among multiple RVA profile characteristics. Amylose content had significantly positively correlation with setback, consistency, pasting temperature, respec-tively, whereas amylose content had significantly or very significantly negative correlation with breakdown and peak viscosity. Protein content had significantly or very significantly positive correlation with trough viscosity and pasting temperature, protein content had no significant correlation with the rest of RVA profile characteristics. The palatability value of cooked rice had very significantly positive correlation with peak viscosity and breakdown. Moreover, the palatability value of cooked rice had very significantly negative correla-tion with setback, consistency, pasting temperature, respectively. RVA profile characteristics could fully reflect the advantage and dis-advantage of eating value, and it could be used as the main basis of breeding fine quality two-line japonica hybrid rice.
