Abstract

Correlations and Path coefficient between seed yield and yield components were estimat- ed in thirty five inbrids of Castor. The genotypic correlations were heigher than the pheno- typic correlation. Number of nodes to main spike, length of main spike, length of female portion, number of effective spike and height of plant and significant postive correlation with yield, Path coefficient analysis revealed that length of female portion, number of nodes to main spike and height of the plant had the maximum direct effect of yield.
