CHARACTERIZATION OF SPELT (TRITICUM-SPELTA L) FORMS BY GEL-ELECTROPHORETIC ANALYSES OF SEED STORAGE PROTEINS .1. THE GLIADINS

A comparison betweeen the electropherograms of the spelt and wheat cul tivars showed specific differences in the gliadin band patterns which provided the possibility of a clear classification into spelt or wheat . A special nomenclature was developed to be able to improve the prese ntation of the gliadin band pattern of spelt, which is different from that of wheat. This nomenclature, however, has not yet been applied to other cereals. The gliadin band patterns were presented in a schemati c form. As a parameter for comparison, idealized band patterns of both wheat and spelt were developed by comparing the proportions of the ba nds of all available types. When comparing the gliadin band patterns o f the spelt cross-breeds with their corresponding parental generations , it was noted that the same parental bands were not always transmitte d and that the cross-breeds showed differences in the intensity, mobil ity, occurrence, and the splitting of single bands. In general it can be said that the band pattern of the daughter generation - even in the examined F-5 and F-6 generations - is more similar to the band patter n of the mother than to that of the father, which proves a maternal ef fect.
