Abstract
Correlation and path coefficient were carried out in F2 and F3 generations of the cross SVPR 1 x DPI 1443 in sesame. Single plant yield showed a positive correlation with capsule number, 1000-seed weight and plant height, and a negative association with percentage seed oil. In both generations, path coefficient analysis revealed the importance of the number of primary branches as a selection criterion for yield improvement. Intermating in the F2 or a later generation was suggested for improving yield and percentage oil simultaneously.
