‘Chamdream’ is a medium-late maturing, high-quality rice cultivar developed in 2014 by the crop breeding team of Crop Research Division, GARES, Hwaseong, Korea, in cooperation with the rice breeding team of the National Institute of Crop Science, RDA, Korea. ‘Chamdream’ was first developed in 2004 from a backcross between the F1 hybrid ‘Samgwang/Jojeongdo’ and ‘Samgwang’ cultivar. The heading date of this cultivar is August 17th in Gyeonggido Province. Its culm length is 79 cm and it has 15 panicles per hill and 115 spikelets per panicle. It is a medium-grain brown rice cultivar with a weight of 22.9 g per 1,000 grains. Its cold tolerance is lower than that of ‘Hwaseongbyeo’ and its degree of lodging tolerance is similar to that of ‘Hwaseongbyeo’. This cultivar is resistant to bacterial leaf blight and stripe virus diseases and moderately resistant to rice blast diseases, but it is susceptible to other virus diseases and pests. The appearance of milled ‘Chamdream’ rice is clear and its protein content is 5.4%, which is lower than that of ‘Hwaseongbyeo’. The palatability of cooked ‘Chamdream’ rice is better than that of ‘Chucheongbyeo’ which is mainly cultivated in Gyeonggido. Its milling ratio is 76.8% which is higher than that of ‘Hwaseongbyeo’. The yield of milled ‘Chamdream’ rice was 5.9 MT/ha in the local adaptability tests in standard cultivation in four regions from 2012 to 2014. ‘Chamdream’ is highly adaptable to the environmental conditions of Gyeonggido Province, especially to the southern region of Han River.
