Abstract: HMW glutenin subunits and genes in Ta. crinitum were investigated by using SDS-PAGE and PCR technology . The results suggested that HMW glutenin in Ta. crinitum were very similar but not identical to those of wheat especially in terms of electrophoresis mobility . The electrophoresis mobility of the x type subunits of Taeniatherum was slower or closer to that of Dx2 of wheat , and of y type subunits were faster than that of Dy12 of wheat . Our results indicated that Taeniatherum species may contain HMW glutenin subunits similar to those of wheat and that the Taeniatherum subunits may have the potential value for improving the end use qualities of wheat .

Key words: Taeniatherum
