벼 종자의 표면에 코팅층을 갖는 코팅 벼 종자로서, 코팅층은 산화철과 스티렌-부타디엔 공중합체 및 메틸 메타크릴레이트-부타디엔-스티렌 공중합체로 이루어진 군에서 선택되는 적어도 1 종의 공중합체를 함유하고, 상기 산화철의 함량은 상기 코팅 벼 종자 100 중량% 에 대하여 30 ~ 90 중량% 인 코팅 벼 종자가 개시되어 있다. 이에 따라, 조해를 받기 어렵고 기존의 철 코팅 벼 종자의 발아율 저하의 문제가 없는 코팅 벼 종자를 제공할 수 있다. Disclosed is a coated rice seed having a coating layer on the surface of a rice seed, wherein: the coating layer includes an iron oxide, and at least one type of copolymer selected from the group consisting of styrene-butadiene copolymers and methyl methacrylate-butadiene-styrene copolymers; and the content of said iron oxide is 30-90 wt% to 100 wt% of said coated rice seeds. Thus, it is possible to provide coated seeds that are less susceptible to bird damage, and that do not have the problem of reduced germination rate as in conventional iron coatings.
