Genotypic variation of phytolectin in Korean land races and wild soybeans

Two thousand and one hundred sixty-five land races and 164 wild soybeans of Korea were determined for the presence or absence of a seed lectin by hemaggulutination and double immunodiffusion. Three type of soybean line, high lectin(LeH), low lectin(LeL), and lacking(le) soybean seed lectin were found in this investigation. In contrast to Glycine max(0.8 %), the larger percentage (67.7 %) of the Glycine sofa were lack of soybean seed lectin. The seed lectin of Glycine soja were identical to Glycine max SBL by the immunologically. Korean and Chinese cultivars were observed in higher frequency of the lacking seed lectin compared with that of soybeans collected from other countries. Korean wild soybean were showed the highest(67.6-69.2%) percentage of the lectinless lines among the collections from various countries.
