Abstract
“Hyangcheola” is a new japonica rice variety developed as a cross between “Joryeong” and “Seolhyangchal” by the rice breeding team at NICS in 2014. The heading date of “Hyangcheola” is July 28 in the middle plain area, which is 8 days earlier than that of “Hwaseong.” “Hyangcheola” has a 76 cm long culm, which is 8 cm shorter than “Hwaseong” and has 86 spikelets per panicle. The viviparous germination rate of “Hyangcheola” was 27.9%. It showed resistance to stripe virus but susceptibility to bacterial blight (K1, K2, and K3 races), dwarf and black streak dwarf viruses and planthoppers. The milled rice of this variety exhibits translucent and medium short grain shape. The protein content of “Hyangcheola” was 8.2%, which was 1.5% higher than that of “Hwaseong.” “Hyangcheola” is a rice with a fragrant aroma. The content of iron in 100 g of brown “Hyangcheola” rice was 15.12 mg, which is 3.69 mg higher than that of “Hwaseong,” and the zinc content was 32.24 mg, which is 8.75 mg more than that of the comparative variety “Hwaseong.” The average milled rice yield of “Hyangcheola” was 4.8 MT/ha at our sites under ordinary cultivation (Registration No. 6807).
