Abstract

English
“Samkwang1,” a japonica rice variety, was developed as a cross between “Samkwang” and F1 of Suwon152 (IT008283), which has a medium maturing and lodging resistance and Samkwang (IT284608), a high quality variety with bacterial blight resistance and mid-late maturing property by the rice breeding team at NICS in 2015. The heading date of “Samkwang1” was August 8 in the middle plain area, which was 2 days early than that of “Hwaseong.” “Samkwang1” had a culm length of 77 cm, which was 7 cm shorter than that of “Hwaseong,”
and it had 128 spikelets per panicle. The viviparous germination rate of “Samkwang1” was 2.1%. “Samkwang1” showed resistance to blast, bacterial blight (K1, K2, and K3 race) and stripe virus, but was susceptible to the K3a race of bacterial blight, dwarf and black streak dwarf viruses, and plant hoppers. The milled rice of this variety exhibits translucent and medium short grains. The cooked rice grains of “Samkwang1” have an excellent palatability index (0.35) and lower protein content (6.2%) than that of “Hwaseong.” The characteristics related to grain
milling were better than those of “Hwaseong,” especially the head rice milling recovery ratio and head rice ratio (94.2%). “Samkwang1” showed 5.62 MT/ha of milled rice productivity at 11 sites under ordinary cultivation conditions (Registration No. 6798).
