Suspension cultures of soybean were initiated from hypocotyl or cotyledon callus tissue of several soybean genotypes. When these were grown on L2 medium with 0.4 mg/liter 2,4-D several genotypes produced numerous embryoids while others produced only a few such structures. Due to internal anatomy, no embryoid developed into a complete plant. A genotype's propensity to form normal appearing embryoids was correlated with the ability to proliferate shoots at the cotyledonary node on a medium with benzylaminopurine as determined in previous testing.
