Correlation Coefficients and path coefficients were computed for yield components in 50 types ot blackgram. The results indicated that all the characters studied showed significant positive association with seed yield at genotypic and phonotypic levels. Pod number and cluster number not only showed high positive association among themselves but also showed positive correlation with other characters with the exception of hundred seed weight. Besides pod yield, pod number was themost important character in deciding the grain yield per plant. Pod length had a negative direct effect, The indirect effect of all the yie'd components via pod length were always negative. The residual effect was of a low magnitude.
