Pull et al. (1978) found five soybean lines ( 'Columbia' , 'Norredo', 'Sooty', Tl02 and 'Wilson-5') lacking the 120,000 dalton seed lectin, also called soybean lectin (SB1) . Orf et al . (1978) established that the lack of SBL is inherited as a simple recessive, le le . The homozygous dominant (Le Le) and heterozygous (Le le) condition result in the presence of SBL.
