This study was carried out to create new popcorn variety. 'G-Popcorn' was made by single crossing with two inbred lines, the seed parent, GP3, and the pollen parent, GP4. The hybrid was made in 2009 and selected in 2014 after investigating characteristics for three years from 2012 to 2014. 'G-Popcorn' was evaluated on 2 or 3 places in Gangwon-do for three years. 'G-Popcorn' showed higher lodging tolerance and popping volume in contrast to the check variety 'Oryunpopcorn'. The plant height is 213cm indicating 5cm lower than that of 'Oryunpopcorn'. Also, ration ear height of plant height of 'G-Popcorn' is 59%. The weight of 100 seeds was 15.5g, similar to that of 'Oryunpopcorn'. The popping volume of 'G-Popcorn' was about 28.3cm/g, higher than 25.0㎤/g of 'Oryunpopcorn'. The yield of 'G-Popcorn' was 467kg/10a in regional yield trials for three years, which was 7% higher than that of 'Oryunpopcorn'.
