Character Association and Path Analysis of Sorghum (Sorghum bicolour L. Moench) Genotypes for Striga Resistance

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 (rp = -0.28, rg = -0.32), DM (rp = -0.27, rg= -0.28) and Stm-2( rp = -0.36, rg = -0.61),SV(rp = -0.48, rg = -0.73) and SSV (rp = -0.37, rg =-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 (rg =0.23*) and thousand kernel weight.
