For field experiments in an effort to elucidate functions of the wheat lectin (wheat germ agglutinin, WGA), the establishment of varieties sharply contrasting in the lectin content is very important. As the starting point for solution of this problem we studied the WGA variability in the seeds of 33 spring wheat varieties obtained in two different breeding centers: Saratov's and Kharkov’s those. The vari ability in response to environment for Saratovskaya 29 was also estimated.
