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 weight(0.79*),head number(0.45*),panicle width(0.29*),and
panicle length(0.26*)Whereas, phenotypically and genotypically negative significant
(P < 0.05) for DF (r_p = -0.28,
r_g = -0.32), DM (r_p = -0.27, r_g= -0.28) and
Stm^-2( r_p = -0.36, r_g = -0.61),SV(r_p
= -0.48, r_g = -0.73) and SSV (r_p = -0.37, r_g =-0.69
), respectively. Generally, positive and significant
genotypic correlation in grain yield (kg ha^-1) showed with head weight, panicle width, above ground biomass, head number (r_g =0.23*) and thousand kernel weight.
