This research aimed to evaluate experimental soybean lines, with the finality to identify genotypes that contine traits of elevate yield and insect tolerance. Plant material included three populations derived from a 4×4 partial diallel having four parents insect resistants and four with elevated yield cultivars. The 24 experiments were carried out in randomized complete block design with two replications subdivided in three sets with common checks, testing the three populations in eight environments. There is genetic variability among lines in the three populations; the management systems were efficient as representative of the environmental diversity; the Anhembi location exhibited with high seed yield in all situations; as for the ability in originating superior lines, the following parents stand out: IAC-100, D72-9601-1, BR-6, Davis, and IAS-5; the best outstanding biparental crosses occurred when the IAC-100 parent was crossed with IAS-5, Davis, OCEPAR-4, and BR-6.
