The objective of this study was to determine whether it was possible to develop in soybean [ G. max (L.) Merr.] seeds double null genotypes for the Kunitz trypsin inhibitor ( ti ) null in reciprocal combinations with genotypes lacking lectin ( le ), lipoxygenase‐1 (/xl), μ‐amylase ( sp 1), and urease ( Eul ‐ sun ). Homozygous double recessive soybean lines were obtained for all eight combinations. From F 2 data collected using colorimetric, immunological, and electrophoretic tests, we demonstrated that the Kunitz trypsin inhibitor locus segregated independently of the lectin, lipoxygenase‐1, urease and α‐amylase loci.
