출수기는 8월 11일로 중부평야에서 흑진주벼 7월 24일보 다 늦는 중생종 품종이다.
간장은 89 cm로 흑진주보다 8 cm 정도 크고, 주당수수는 흑진주벼와 비슷한 14개이며 수당립수는 122개로 흑진주 100개보다 많다. 현미천립중은 17.0 g 이다.
도열병에는 강하지는 않으나 흰잎마름병에 강하고 줄무늬 잎마름병은 중정도로 강하다.
불시출수는 없고 성숙기 하엽노화는 흑진주벼와 같이 늦 으며, 수발아는 6.6%로 적은 편이다. 내냉성과 도복은 약 한 편이다.
전국 7개 장소의 평균 현미수량은 4.75 Mt/ha 이다.
아밀로스 함량은 19.7%로 메벼이며 향이 흑진주벼에 비하 여 강하다.
현미색은 진한 검정색으로 안토시안 함량은 136 mg/100g, 항산화 성분인 폴리페놀 함량은 529 mg/100g 이다.
재배적응 지역은 중부평야 및 호남평야이다.
