‘Jungdream’ is an early maturing, high-quality rice cultivar developed in 2017 by the crop breeding team at Crop Research Division,GARES, Hwaseong, Korea. ‘Jungdream’ was first developed in 2008 from crossing a medium-late maturity cultivar ‘Chilbo’ and an early maturitycultivar ‘Ungwang’. The heading date of this cultivar is July 28thin the Gyeonggido Province. Its culm length is 63 cm, and it has 19 paniclesper hill and 82 spikelets per panicle.

The appearance ofmilled ‘Jungdream’ rice is clear, and its amylose content is 16.5%, which is lower than that of ‘Hwaseong’. The palatability of cooked ‘Jungdream’rice is better than that of ‘Chucheong’, which is the main cultivated crop in Gyeonggido. Its milling ratio is 75.0%, which is lower than thatof ‘Hwaseong’. The yield of milled ‘Jungdream’ rice was 5.42 MT/ha in the local adaptability tests during standard cultivation in four regionsfrom 2015 to 2017. ‘Jungdream’ is highly adaptable to the environmental conditions in the Gyeonggido Province (Registration No. 8236).
