Abstract :Association and path analysis of yield related traits is essential for breeders. The objectives of this study was to investigate the relationship among yield, yield related traits and Striga parameters. The experiment was conducted at Kobo research sub-center, North eastern Ethiopia in 2018 main cropping season using simple lattice design. Phenotypically positively significant traits were head weightinsert ignore into journalissuearticles values(0.79*);,head numberinsert ignore into journalissuearticles values(0.45*);,panicle widthinsert ignore into journalissuearticles values(0.29*);,and panicle lengthinsert ignore into journalissuearticles values(0.26*);Whereas, phenotypically and genotypically negative significant insert ignore into journalissuearticles values(P < 0.05); for DF insert ignore into journalissuearticles values(r p = -0.28, r g = -0.32);, DM insert ignore into journalissuearticles values(r p = -0.27, r g = -0.28); and Stm -2 insert ignore into journalissuearticles values( r p = -0.36, r g = -0.61);,SVinsert ignore into journalissuearticles values(r p = -0.48, r g = -0.73); and SSV insert ignore into journalissuearticles values(r p = -0.37, r g =-0.69 );, respectively. Generally, p ositive and significant genotypic correlation in grain yield insert ignore into journalissuearticles values(kg ha -1 ); showed with head weight, panicle width, above ground biomass, head number insert ignore into journalissuearticles values(r g =0.23*); and thousand kernel weight.
