Characteristics of Agronomy to Selected 3 Lines from Native Green Waxy Rice(Oryza sativa L.)

In order to find out better cultivation practices for environmentally-friendly agriculture, an experiment with four fertilizer levels and one cultivar, 'Boseokchal', and three lines, GG-05-03, GG-05-04, and GG-05-07 was carried out. Those lines had been selected from native green waxy rice over a period of five years (2004~2008). The tillering numbers of both the GG-05-03 and GG-05-04 lines were similar, but GG-05-07 was less than those. Regarding plant height, both GG-05-04 and GG-05-07 were higher than 'Boseokchal', while GG-05-03 was similar to it. There was no marked difference of quantitative character amond the three lines regarding grain weight and grain number of ear. 1000-grain weights of all three lines were slightly light compared to 'Boseokchal' cultivar. Head rice yields of both the GG-05-03 and GG-05-07 lines were less than 'Boseokchal', but the GG-05-04 line was similar to it. Only total lipids of all compositions of brown rice showed a slightly different rate compared to 'Boseokchal'. These results summarize that the GG-05-07 line was shown to be better than both the GG-05-03 and GG-05-04 lines for environmentally-friendly agriculture practices.

재래종 녹색현미찰벼로부터 선발한 3 계통의 농업적 특성

친환경적으로 우수한 품종을 찾고자 4개 시비 처리구와 1개 품종, '보석찰'과 재래종 녹색현미찰로부터 선발한 3 계통으로 실험을 행하였다. 각 비료시비구당 계통별 분얼수는 GG-05-03과 GG-05-04는 유사하고 GG-05-07은 적었다. 계통별 초장은 '보석찰'에 비해 GG-05-04와 GG-05-07은 다소 크고, GG-05-03 유사하였다. 이삭당 낟알의 무게와 낟알수는 계통별 큰 차이가 없었다. 임실율은 계통별 차이가 없었으나 천립중의 경우 '보석찰' 보다는 가벼웠다. 수량은 '보석찰'과 비교하였을 경우 GG-05-03과 GG-05-07은 다소 적고, GG-05-04는 유사하였다. 미질은 '보석찰'과 비슷하고 조지방에서 차이를 다소 보였다. 이상의 결과를 요약하면 GG-05-07 계통이 보다 친환경적 재배에 유용한 것으로 나타났다.
