Abstract: Using ten rice varieties, the characters of leaf type and yield component in heading stage were investigated , and the relationship between them were analyzed: (1)The leaf length and leaf width were different in ten rice varieties; (2)The leaf angle was discrepant in ten rice varieties; (3)With the N concentration supplied increasing, the leaf angle and leaf width increased, and leaf length increased first then decreased; (4)The relationship between seed setting rate and leaf angle was positive correlations, and the relationships between grain weight and leaf angle and grains per spike and leaf angle were negative correlations; (5)The relationship between grain weight and leaf length was positive correlations, and the relationships between seed setting rate and leaf length and grains per spike and leaf length were negative correlations.
