영문 초록

In order to test varietal compatibility, 76 Japonica varieties were crossed to the Tongil type test varieties, Gayabyeo and Milyang 42, and 59 Tongil type or Indica varieties were crossed to the japonica test varieties, Samnambyeo and Milyang 74. Two wild rices, WSP 624 and O. nivara/O. sativa, were crossed to the above four testers. After growing the F₁ plants, the pollen and spikelet fertility were tested. The Tongil type tester Gayabyeo showed relatively high compatibility to the Japonica varieties, however, Milyang 42 showed low compatibility to those. Among the Japonica varieties tested, Nagoyudaka, Gou 1 and Gou 2 were relatively high compatible to Tongil type testers. The Japonica testers Samnambyeo and Milyang 74 did not show high compatibility to Tongil type or Indica varieties. The rice varieties Dourado Precose from Brazil, Huan-Sen-Goo from Taiwan, Kataktara DA 2 from Bangladesh, Azucena from Philippines, NP 125 and Dular from India, TOX 1785 from IITA, Dawn and Zenith from USA were highly compatible to the Japonica testers, Samnambyeo and Milyang 74. The Tongil type variety Gayabyeo was highly Compatible to the wild rices tested.
