Genotypic and Phenotypic Relationship among Yield Components in Rice under Tropical Conditions

Figure 1

Path diagram and coefficients of factors on the influence of first-order on second-order components and the latter on yield per hectare, ij values are the direct effects, and rij values are the correlation coefficients. Note: in the path diagram, the single arrowed lines represent direct influence while the doubled-arrowed lines indicate a mutual association.
