우리나라는 2007년부터 벼 DUS-Test를 위한 표준품종 선정에 관하여 국제미작연구소가 주관하는 국제연락시험(INEVDUST)에 참여하고 있으며 벼 재배국가에서 공통으로 사용할 표준품종 선정을 위한 2007-2008년 동안의 시험결과를 요약하였다.76개의 품종을 이용하여 수원에서 출수된 56품종에 대해UPOV Guidelines를 기준으로 엽이색, 생육일수 영의 윤활도등 16개의 주요특성을 조사한 결과 엽이가 자색인 것은 WC1240, IR 69682-132-1-1-2 등 2품종, 매끄러운 영은 DV35,K 39-96-1-1-1-2 등 8품종, 줄기의 마디가 자색인 것은 K39-96-1-1-1-2 등 3개 품종이었다. 출수일수는 116-115일 사이에다수가 분포하였고 이삭의 형태는 약간 숙여지는(Semi-uplight)것이 48%를 차지하였고 지경의 형태는 반직립(Semi-errect)의 것이 61%, 장폭비는 2.6-3.5에 해당하는 품종이 가장 많았으며 56개의 품종은 16개의 형질을 변수로 하여 6개 그룹으로 구분되었다.
This study was carried out to evaluate field performance of example rice varieties in multi-location for DUS-test. We are participating in the International Nursery Test for Selecting Example Varieties for Distinctness, Uniformity, and Stability Test(INEVDUST) as one of items in International Network for Genetic Evaluation of Rice(INGER) organized by IRRI. During 2007-2008, 56 example varieties were investigated based on UPOV Guidelines for 16 agronomic characters such as leaf anthocyanin coloration of auricles, time of heading, attitude of blade in flag leaf, density of pubescence of lemma, antocyanin coloration of apex in lemma, color of stigma, stem length, antocyanin coloration of nodes, distribution of awns in panicle, length of main axis in panicle, panicle attitude in relation to stem, attitude of branches in panicle, decorticated grain length, grain width, grain shape, grain color and grain aroma. Auricles of WC 1240 and IR 69682-132-1-1-2 were purple coloration and eight varieties like DV35, K 39-96-1-1-1-2 had smooth hull. Purple nodes in stem were observed in K39-96-1-1-1-2, DV 85 and WC 1240. The peak of heading days was between 111-120 days. Semi-uplight type in panicle attitude in relation to stem occupied 48% and semi-errect type in panicle attitude of branches was 61%. 56 example varieties were divided into six groups with parameters of 16 traits.
