초록

농가포장에서 발생하는 벼 이형주군별 발생포장 비율과 발생량 및 형질특성은 다음과 같다. 1. 우리나라의 지역별 발생포장 비율은 남서부, 남동부, 중부지방 순 이었고, 발생량은 남부지방이 중부지방보다 많았다. 2. 우점 이형주군은 단립적미군, 극만생 불임군, 장립적미군 순이었고, 장립적미군은 전남과 경남, 극만생 불임군은 전북, 단립적미군은 나머지 지역에서 우점하였다. 3. 대부분 이형주군의 간장은 인근 농가의 재배벼보다 길었는데, 특히 장립적미군과 단립적미군이 길었다. 4. 수당 영화수는 이형주군이 재배벼보다 많은 경향이었는데, 특히 극만생 불임군과 장립메성군이 많았다. 그러나 이형주군들은 대체로 불임이 심했다.

This study was carried out to investigate the distribution and characteristics of off-type rice plant in farmer's paddy field. The ratio of the field contaminated by off-type rice was highest in the southwestern area, followed by the southeastern area, the central area in Korea. The occurrence density of off-type rice was higher in the southern area than the central area. The short-grain red rice was the most dominant off-type rice group, followed by extremely late and sterile rice group and long-grain red rice group in Korea. The long-grain red rice group was dominant in Jeonnam and Kyongnam, and the extremely late and sterile rice group was dominant in Jeonbuk, and the short-grain red rice group in the other provinces. The culm length of most off-type rice groups growing in the farmer's paddy fields was longer than the farmer's cultivars, and the long-grain red rice group and the short-grain red rice group were especially longer. The number of spikelets per panicle of the off-type rice groups were generally greater than the farmer's cultlvars, and in particular, the extremely late and sterile rice group and the long-grain normal rice group had more spikelet per panicle. Most of the off-type rice groups were extremely sterile.
