Abstract: The aim of the work was to employ general and specific combinatorial capacity to select possible genetic bases and parents that meet the agronomic ideotype of soybean precocity and grain yield. The experiment was conducted at the Regional University of the State of Rio Grande do Sul. The experimental design used was that of augmented blocks, with interspersed controls, with treatments distributed in four blocks allocated throughout the experiment. To reduce pod insertion height, specific breeding strategies are suggested. For the ideal plant height, line 195 is selected. Lines 262 and 286 are chosen for their early maturity traits, while lines 893 and 661 are selected to improve grain weight per plant. These selections aim to enhance plant growth and yield. The general and specific combining capacity allows the selection of additive and complementary gene constitutions for insertion height of the first pods with the parents Massal Maradona RR 15b70 IPRO, plant height with HO Puricá x HO Jacuí IPRO, precocity through TMG 7262 RR x 15b70 IPRO, grain yield attributes through NS 6700 IPRO x BMX Valente 6968 RSF and DM 7.0 BMX Magna x BMX Ativa RR.
