An Early Maturing and Low Amylose Rice Variety ‘Gawagi1’ Adaptable to the Northern Regions of Gyeonggido Province, South Korea

Abstract

Gawagi1’ is an 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 from the cross between ‘Baegjinju’ and ‘Sangmibyeo’ in 2004. Heading date was 4th of August 15 day earlier than ‘Baegjinju’ in Gyeonggido. The culm length was 67 cm. It had 15 panicles per hill and 104 spikelets per panicle. It is a medium-grain variety whose 1,000 grains weight of brown rice is 19.3 g. The 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.
