영문 초록

The ‘Jungmo1023’ is the japonica rice variety developed from a cross between Yeongdeog34 and F1 of Iksan456 and SR21097-B-B-19-2-2 by the rice breeding team at NICS in 2012. The heading date of ‘Jungmo1023’ is August 3 in middle plain area and it is six days earlier than ‘Hwaseong’. ‘Jungmo1023’ has 80 cm of culm length which is 4 cm shorter than those of ‘Hwaseong’ and 107 spikelet per panicle. The premature heading rate of ‘Jungmo1023’ was 3.3%. It showed resistance to blast, bacterial blight (K1, K2, K3 race) and stripe virus, but susceptibility to K3a race of bacterial blight, dwarf and black streak dwarf viruses and planthoppers. The milled rice of this variety exhibits translucent and medium short grain shape. It has better palatability index of cooked rice (0.24) and lower amylose content (18.0%) 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 (96.2%). ‘Jungmo1023’ showed 4.56 MT/ha of milled rice productivity at 7 sites in ordinary cultivation. However, ‘Jungmo1023’ showed early cultivation culture adaptability because of 98% of its yield potential (4.99 MT/ha) compared to high yielding early-maturing variety ‘Jopyeong’. ‘Jungmo1023’ could be adaptable to the middle plain, mid-mountainous and north-east coastal area in Korea (Registration No. 5115).
