Abstract
‘Jungmo1033’, a japonica rice variety, was developed by the rice breeding team at the National Institute of Crop Science (NICS) in 1992. It is derived from a cross between a native variety ‘Jagwangdo’, which has translucent milled rice and medium maturity; and ‘Hwayeong’, which is an elite line with bacterial blight resistance and mid-late maturity. The heading date of ‘Jungmo1033’ was August 10 in the middle plain area of Korea, which was two days later than that of ‘Hwaseong’. ‘Jungmo1033’ has a culm length of 79 cm, which was 5 cm shorter than that of ‘Hwaseong’, and 105 spikelets per panicle. ‘Jungmo1033’ showed resistance to bacterial blight (K1, K2, and K3 races) and stripe virus, but susceptibility to the K3a race of bacterial blight, dwarf and black-streaked dwarf viruses, and planthoppers. The milled rice of this variety exhibited translucency and a medium short grain shape. It had an excellent appearance and lower amylose content (19.1%) than that of ‘Hwaseong’. The characteristics related to grain milling were better than those of ‘Hwaseong’, especially head rice milling recovery ratio and head rice ratio (94.8%). ‘Jungmo1033’ showed a milled rice productivity of 5.38 MT/ha at 11 sites under ordinary cultivation conditions.
