Abstract

This study was carried out to develop of macro-protocol and the biosafety guide for 'Nakdong', and 'Golden Rice' (genetically modified vitamin A rice) by large scale field trial of GM crops. Typically, when a new GM crop is created, breeders should conduct field test to make sure the GM crop is safe, and provide some information on GM crops for approval. A total of isolated 4,700 $m^2$ field for trial of GM crops were prepared, and 'Nakdong' and 'Golden rice' were cultivated by standard method of RDA (Rural Development Administration, Korea). Field studies indicated that the population densities of insect pests and natural enemies have no difference between two varieties. While insect pest density on 'Nakdong' was slightly higher than on Golden Rice, but natural enemy density on Golden Rice was a little higher. These results provided the insect diversity for risk assessment analysis of Golden Rice and suggested that the macro-protocol could be useful to detect GM plants.

본 연구는 대규모 GMO 격리포장에서 비타민 A 영양성분이 강화된 황금벼의 안정성 평가에 대한 가이드라인 및 프로토콜을 개발하고자 모본으로 사용된 '낙동'을 대조로하여 수행하였다. 경북대학교 농업생명과학대학 GMO 실습격리포장 에서 총 사용면적 4,700 $m^2$에서 황금벼와 모품종인 '낙동'에 대해 거미류를 포함한 곤충류 다양성을 조사하였다. 조사기간 동안 채집된 개체들은 기능별로 해충군, 천적군, 거미군으로 크게 구분하여 계수하였으며, 조사된 개체군의 해충군, 천적군, 거미류 등의 밀도는 기능군 별로 황금벼와 '낙동'간에 유의성을 보이지 않았다. 해충의 발생양상을 비교 분석한 결과 전반적으로 '낙동'에서 발생량이 다소 많은 경향으로 나타났으며, 일부 시기를 제외하고는 대부분의 시기별 평균 간의 차이는 없는 것으로 나타나 황금벼와 '낙동'과의 해충 발생양상에는 유의성을 찾기가 어렵다고 판단된다. 또한 천적류 발생 양상은 해충과는 달리 황금벼에서 발생량이 다소 많은 경향으로 나타났으나, 시기별 평균 간 차이는 없는 것으로 분석되어 천적 발생양상에는 특이한 유의성을 없다고 판단된다. 따라서 비타민 A 영양성분이 강화된 황금벼에서의 해충 및 천적의 개체군 밀도 및 발생양상은 모본인 '낙동'에서와 차이가 없는 것으로 조사되었다.
