Abstract
We evaluated homozygous populations froin 2‐way adapted × exotic and 3‐way (adapted × exotic) × adapted soybean ( Glycine max (L.) Merrill) crosses for seed yield. The average yield of our 3‐way populations was significantly greater than the 2‐way population mean, but differences were not significant in some 2‐, 3‐way sets. Mean population performance was generally predictable from parental performance, although a masking inhence of genes from the third parent was observed in the 3‐way crosses. Estimates oC genetic variance for 3‐way populations generally were larger than for 2‐way populations for yield. Transgressive segregation was observed in all populations, but in most 2‐, 3‐way sets, the 3‐way cross produced more of the superior lines for yield than the 2‐way cross.
