Abstract

This study was carried out to investigate the agronomic traits, comparison of weed characteristics and possibility of gene flow in 'vitamin A enforced GM rice' and the donor plant, 'Nagdong'. The GM rice was not significantly different agronomic traits compared to the donor plant, Nagdong. Weed population changes were investigated in the cultivation of the GM rice and the donor plant, Nagdong. Dominant weed species and their dry matter did not show the difference between GM rice and the donor plant, Nagdong in macro-GM crop field. Dominant weed species with the GM rice and the donor plant, Nagdong were Monochoria vaginalis, followed by Eleocharis kuroguwai, Echinochloa crus-galli and Lindernia procumbens. The detection of gene from the GM rice was done using PCR, gene flow can't be detected by weed species. Results of this study on the agronomic traits, weed characteristics and possibility of gene flow has elucidated that GM rice might not be different from the donor plant, Nagdong.

이 연구는 비타민 A 강화벼(GM 벼)와 모품종인 낙동 및 일반품종을 대조로 농업적인 생육특성과 잡초를 대상으로 유전자 전이 정도를 조사하였다. GM 벼의 농업적인 특성에서 모품종인 낙동과 차이를 보이지 않았으며, 우점 잡초군과 건물중에서 유의성이 보이지 않았다. GM 벼와 모품종인 낙동 재배구의 우점 잡초는 물달개비, 올방개, 좀개구리밥, 물피 등의 10여 종이었다. 잡초의 유전자 전이 정도를 PCR 분석 결과, GM 벼와 낙동 그리고 우점잡초 8종에서 유전자 전이가 나타나지 않았다. 그러므로 비타민 A 강화벼의 화분이 비래하여 비표적 다른 품종의 벼 또는 주변 잡초에 유전자 이동이 일어나 외래유전자가 함유된 잡초가 출현하는 경우는 거의 없을 것으로 사료된다.
