This experiment was conducted to evaluate the variability of hypocotyl elongation of mungbean varieties. With four mungbean cultivars, which were classified as 4234-697 and Keumsungnogdu(long), Nampyungnogdu(Medium), and Seonhwanogdu(short), hypocotyl elong-ation was measured 4 to 6 days after seeding in paper towel at different temperatures (15, 20, 25, 30, and 35$^{circ}C$). Hypocotyl elongation of mungbean seed stored at 5$pm$1$^{circ}C$ for 6 months was compared with of seed stored at room temperature. As the temperature rises, the hypocotyl is longer. The hypocotyl elongation started immediately at high temperature, and longest at the range of 30 to 35$^{circ}C$. The hypocotyl elongation became longer at the 5$^{circ}C$ storage plot than at the room temperature plot. Correlation coefficient (r) between 100 seed weight and hypocotyllength are not significant.
