Present study was conducted during kharif, 2015 at APRRI & RARS, Maruteru with an objective to establish the nature of relation between grain yield and yield components by partitioning the correlation coefficients between grain yield and its components into direct and indirect effects by using simple correlation and path analysis on 114 F5 families from six crosses along with their seven parents. Data was recorded on ten characters which showed significant differences among themselves. The study of character association and path coefficient analysis indicated that panicle length had positive direct effect coupled with positive significant correlation with grain yield per plant and hence direct selection can be made based on this trait for improving yield
