An experiment was conducted at All India Co-ordinated Research Project on Tuber crops, Horticultural Research Station, Dr. Y.S.R. Horticultural University, Venkataramannagudem, Andhra Pradesh during the period 2015 to 2016 to investigate the interrelationship of yield related characters and extent of their contribution to tuber yield in cassava. Correlation Analysis revealed that tuber yield (t ha-1) had significant and positive correlation with total leaf area, plant dry matter content, tuber dry matter content, number of leaves per plant, plant height, stem diameter, number of storage roots per plant, number of commercial roots per plant, tuber length, tuber diameter and harvest index at both phenotypic and genotypic levels, indicating the importance of these traits in selection for yield. Path coefficient analysis revealed that stem diameter and tuber diameter exerted a high positive direct effect on tuber yield (t ha-1). The high direct effect of these traits appeared to be the main factors for their strong association with tuber yield per hectare. Hence, direct selection for these traits should be effective indicating the effectiveness of direct selection.
