'Hwangmichal', a Yellow Waxy Corn F1 Hybrid with High Carotenoid Content

Hwangmichal, a yellow waxy corn hybrid, is a single cross hybrid developed in 2014. This hybrid was created by crossing the seed parent KY30 and pollen parent KY9. Hwangmichal has yellow kernels with a conico-cylindrical ear shape. The days to silking of Hwangmichal were similar to that of Ilmichal, a check hybrid. The ear height ratio of Hwangmichal was 50%, which was lower than that of Ilmichal, and its number of tillers was less than that of Ilmichal. The ear size of Hwangmichal was smaller than that of Ilmichal and the kernel set ratio was 89%. Its sensory evaluation was better than that of Ilmichal. The carotenoid content of Hwangmichal was $32.2{\mu}g/g$, which was much higher than that of Ilmichal. Lodging resistance of Hwangmichal was better than that of Ilmichal. Although the number of fresh ears of Hwangmichal was more than that of Ilmichal, the weight of fresh ears was lower than that of Ilmichal. The flowering period of its parent lines was well matched and seed production was 3:1 at a planting density of parent lines of more than 2:1. It is adaptable to the whole country except for Jeju-do. The plant variety protection right of Hwangmichal was registered in June 2017, and its grant number is 6728.

카로티노이드를 함유한 노랑찰옥수수 '황미찰'

황미찰은 2014년 농촌진흥청 국립식량과학원에서 개발한 단교잡종 찰옥수수로 이삭의 색깔은 노란색이며 자식계통 KY30을 종자친으로 하고 KY9를 화분친으로 한다. 황미찰의 출사일수는 일미찰(표준품종)과 유사하였고 이삭길이는 18.4 cm, 이삭직경은 4.3 cm로 일미찰보다 작았으며 착립장률은 89%로 일미찰보다 낮은 수준이었다. 아밀로펙틴함량은 90.9%로 일미찰과 유의한 차이가 없었고 과피두께와 백립중, 립장, 립폭 등 알곡의 특성 또한 일미찰과 유사하였으며 카로티노이드 함량은 $32.2{\mu}g/g$로 일미찰보다 높았다. 황미찰의 내병충성은 일미찰과 유사하였으며 내도복성은 일미찰보다 우수하였다. 황미찰의 단위면적당이삭수는 일미찰보다 많았고 이삭중은 낮았으며 채종시험결과 종자친과 화분친간 개화기는 잘 일치하였고 모 부본 재식비율을 3:1에서 가장 높은 채종량을 나타내었다.
