Abstract:Gliadin and glutenin of seeds of a pollen-derived pure line “H-33” and its 9 stable somaclones of wheat (Triticum aestivurn L.) from inflorescence callus were investigated using SDSPAGE. Among the 9 somaclones 6 were identical to the “H-33” in SDS-PAGE patterns of of gliadin and glutenin. The other 3 somaclones were identical with each other, but different from “H-33”. The varied electrophoretic bands of seed protein showed that somaclonal variation had occured at gene level during tissue culture in which the somaclones were produced.
