Variability in Seed Protein of Two f:ultivated Species of Barnyard Millet Through SDS-PAGE

Abstract

Seed protein variability of four barnyard millets belonging to two cultivated species viz., Echinochloa frumentacea and E. crusgalli ssp. utilis were examined through SDS-PAGE. Morphological traits and potentiality of high seed setting at different environments (March, April, May and June sowing) indicated that the latter showed resistance! tolerance to cold and smut disease of grain at high altitudes (2100 m and above) of Himalayas. Differences in banding patterns and intensity in colour of bands revealed that characterization and identification of genotypes belonging to these two cultivated species is possible through analysis of protein subunits.
