Inheritance of a Soybean Seed Lectin¹

Abstract

Soybean [ Glycine max (L.) Merr.] seed from the reciprocal crosses of ‘Amsoy’ and T102 were used to study the inheritance of the soybean seed lectin (SBL) having a molecular weight of 120,MH). Amsoy contains SBL while T102 lacks SBL. From data collected using polyarcylamide gel electrophoresis the presence of SBL is controlled by a single dominant gene designated Le . The homozygous recessive le le results in the lack of SBL. The availability of soybean lines lacking SBL may aid in determining the role and function of SBL.
