Abstract The leaf SPAD reading and hue angle（H°）of both leaf and fruit in 26 Momordica charantia L. inbred lines were measured by Minolta SPAD-502 and Minolta chroma meter CR-300，respectively．The correlations between leaf SPAD reading，leaf color and fruit color were calculated．The results indicated that leaf SPAD reading，leaf color and fruit color have very significant differences in different bitter gourd inbred lines．Meanwhile，both leaf SPAD reading and leaf color showed a significant correlation with fruit color，and leaf color was very significantly correlated with leaf SPAD reading.
