Abstract

‘Haedeul’ is a high-quality rice variety with early maturing that adapts to the central region of Korea. This cultivar was crossed between ‘Gopum’, which has excellent taste, and ‘Hoban’, which has a low viviparous germination rate and is moderately tolerant of cold, by the rice breeding team of the Department of Central Area Crop Science, NlCS, RDA, in 2017. In early-transplanting cultivation, the heading date of ‘Haedeul’ was July 24 in central area of Korea, which was seven days later than that of ‘Jopyeong’. ‘Haedeul’ had a culm length of 75 cm and 99 spikelets per panicle. The viviparous germination rate of ‘Haedeul’ was 7.7%. It showed resistance to blast and bacterial blight (K1, K2, K3 race), but was susceptible to the K3a race of bacterial blight, stripe virus, dwarf and black streak dwarf viruses, and plant-hoppers. The milled rice of this variety exhibited a translucent and medium short grain shape. The cooked rice grains of ‘Haedeul’ had an excellent palatability index (0.61) and lower amylose content (18.0%) than that of ‘Jopyeong’. The grain milling characteristics were better than those of ‘Jopyeong’, especially the head rice milling recovery ratio and head rice ratio (94.9%). ‘Haedeul’ milled rice productivity averaged 5.32 MT/ha at five sites under ordinary cultivation.
