영문 초록

This study is carried out to test affinity of the Korean red rices with Indica and Japonica cultivars, and with foriegn red rices. Two types of Korean red rices, long grain and short grain type, were crossed to the Indica cultivar IR 26 and IR 50, and to the Japonica cultivar Keumobyeo and Shin 2. The long grain type Korean red rice were crossed to the short grain type Korean red rices. Two types of Korean red rices were crossed to the Chinese red rices from Anhui province, 85-27 and 85-48, and to Javanica red rice Malagkit Sinaguing and Indica red rice Khonorullu. The F₁s of the crosses were grown in field condition, and spikelet fertility were investigated. Spikelet fertilities of the F₁s between the long grain Korean red rices and Indica testers IR 26 and IR 50 were 50.7% and 46.2%, and those between the long grain Korean red rices and Japonica testers Geumobyeo and Shin 2 were 21.4% and 32.3% respectively. Spikelet fertilities of the F₁s between the short grain Korean red rices and Indica testers IR 26 and IR 50 were 32.4% and 41.8%, and those between the short grain Korean red rices and Japonica testers Geumobyeo and Shin 2 were 54.2% and 64.8% respectively. Thus affinity of the long grain Korean red rices with Indica was closer than with Japonica and that of short grain Korean red rices with Japonica testers was closer than with Indica. The F₁s crossed between the long and short grain Korean red rices showed about 50% spikelet fertility. The F₁s between the long grain Korean red rices and the Chinese red rices from Anhui province showed almost normal fertilities. Thus, the long grain Korean red rices and the Chinese red rices from Anhui province were proved to be very close in affinity.
