Abstract: Correlation coefficients between agronomic characters and biochemical matter contents in flower buds and leaves, between biochemical matter contents in flower buds and that in leaves, between every two groups each other among the biochemical matter contents in flower buds and between these in leaves of CMS hybrids were estimated in pepper. Results showed that the contents of soluble sugar and soluble protein and POD activity in leaves have bigger correlation with plant characters, the contents of free proline and IAA in leaves have bigger correlation with fruits characters. The content of soluble sugar and POD activity in flower buds have bigger correlation with fruits characters, the contents of IAA in flower buds have bigger correlation with plant characters. The contents of soluble sugar, free proline and soluble protein in flower buds have bigger correlation with these in leaves, but the vise versa for the contents of IAA, ABA and ZRs and POD activity.
