초록
‘Gawagi1’ is a new early maturing, low amylose rice variety with a medium to short culm, developed by Gyeonggi-Do Agricultural Research & Extension Services, Hwaseong, Korea in 2016. ‘Gawagi1’ was derived 1 from a cross between ‘Baegjinju’ and ‘Sangmibyeo’ in 2004. This variety headed on the 4th of August which was 15 days earlier than ‘Baegjinju’ in Gyeonggido. Its culm length was 67 cm. This variety had 15 panicles per hill and 104 spikelets per panicle. It is medium-grain variety that 1,000 grains weight of brown rice is 19.3 g. Its protein content of milled rice was 6.3%, which is higher than that of ‘Baegjinju’ and its amylose content was 8.2% which is lower than that of ‘Baegjinju’. Its milling ratio is 75.5%, which is higher than that of ‘Baegjinju’. The yield of milled rice was 4.99 MT/ha under the standard cultivation practices at the local adaptability tests in 3 regions from 2014 to 2016. ‘Gawagi1’ is highly adaptable to Gyeonggido, especially to the northern region of Han River.
