A crop seed yield varies between genotypes. The seed yield diversity among sorghum genotypes was hypothesized to be affected by the difference of the genes and agronomic characters among genotypes. An experiment that aimed to know the relationship model between agronomic characters of various sorghum genotypes and its seed yield has carried out in May-September 2015 in Pekon Solokarto, Sub-District of Gadingrejo, District of Pringsewu, Lampung Province, Indonesia (5.36 ᵒS; 105.03 ᵒE) using 34 genotypes. The experiment used a randomized complete block design (RCBD) with three blocks as three replicates. Path analyses was used to know the direct and indirect effects of agronomic character variables to a seeds yield variable. There were five characters those directly affect to seed yield measured by seed weight per plant (SWPP), those were stem height (SH), stem dry weight (SDW), leaf dry weight (LDW), seed number per panicle (SNPP), and weight of thousand grains (WTG). The agronomic character that indirectly affected to seed yield via stem dry weight was root dry weight (RDW). The agronomic characters those did not affect to SWPP were leaf number (LN), dry weight of flag leaf (DWFL), and dry weight of panicle (DWP). The relationship model of agronomic characters of sorghum and its seed yield was SWPP = -11,3674 + 1,3988LDW - 0,5947RDW - 0,0838SDW + 0,1419SH - 0,2259WTG +0,0128SNPP with R² = 0,79 (P<0,001). Keywords: seed weight per plant, stem height
