초록
밀양 204호는 작물과학원 영남농업연구소 생명공학연구팀이 직파적응 제초제저항성 벼 품종을 육성할 목적으로 ’98년 bar 유전자를 동진벼에 아그로박테리움법으로 형질전환하여 제초제저항성 벼를 양성하였다. ’98/’99년 동계에 단간 내도복 양질인 주남벼를 인공교배하여 약배양 등 육종프로그램에 적용하여 우량계통을 선발하고 밀양 204호로 계통명을 부여하였다. GM 벼와 Non-GM 벼의 농업적 특성을 UPOV 및 국립종자관리소의 품종등록 기준에 따른 농업적특성 중 차이가 있었던 것은 엽색도, 지엽의 형태, 간장, 수당립수 등 이었다.
Abstract
This study was conducted to investigated the major characteristics of genetically modified rice of Milyang 204 originated from Dongjinbyeo compared to a non-transgenic rice varieties Dongjinbyeo and Junambyeo. Basta resistant transgenic rice lines carrying bar gene produced by the Yeongnam Agricultural Research Institute were evaluated for their agronomic characters. The transgenic Japonica rice of Milyang 204 showed inferior phenotypic traits compared to a non-transgenic rice variety Dongjinbyeo and Junambyeo. On the basis of UPOV (Union Internationale Pour la Protaection des Obtentions Vegetables) and NSMO(National Seed Management Office) the transgenic Milyang 204 showed difference in some traits out of some agronomic traits, such as leaf color, angle of flag leaf, number of spikelets, culm length, white core and white belly compared to the non- transgenic varieties rice.
