Sorghum seed is traditionally used as health supplements and the secondary food mixed with rice in Korea. While the research of reserve protein in sorghum seed have been carried out in many countries used as major food, much less is known about reserve proteins of Korean local sorghum seeds. To obtain protein characteristics in 20 Korean local sorghum seed, quantitative content of reserve protein was determined after fractionation by modified ‘Osbone’ method and α-kafirin of prolamin was determined by SDSPAGE. Mean albumin, globulin, prolamin and glutelin contents based on total seed protein content of 20 Korean local sorghum seed were 6.2%, 0.9%, 57.9% and 35.1%, respectively. Sorghum cultivar with high prolamin were ‘Whin-susu’, ‘Whin-Chalsusu’, ‘Whanggeum-Chalsusu’, and ‘Daepungshushu’. Sorghum cultivar with high α-kafirin were ‘Whin-susu’, ‘Geumsan-Chalsusu’, ‘Whin-Chalsusu’, and ‘Jangmok-susu’. Among the 20 varieties, ‘Whin-susu’ and ‘Whin-Chalsusu’ were selected as high α -kafirin and prolamin sorghum cultivar, which showed 64.5 and 71.9% of prolamin contents, respectively.
