Pull et al. (1978b) screened 102 lines of soybeans [Glycine max (L.) Merr.] and found 5 lines lacking the 120,000 dalton seed lectin ('Columbia', 'Norredo', 'Sooty', 'T102', and 'Wilson-5'). The amount of soybean lectin (SBL) per g defatted meal and the amount of SBL content in soybean protein for the 102 lines tested also was published by Pull et al. (1978a). Orf et al. (1978) demonstrated, using polyacrylamide gel electrophoresis, that the presence of SBL is controlled by a single dominant gene designated Le. The homozygous recessive le le results in the lack of SBL.
