초록

국내 옥수수 유전자원을 계통육성하여 충남대학교 옥수수 유전 육종 실험실에서 새로 작성된 찰옥수수 교잡종을 2009년 5윌에 본 대학 옥수수 육종포장에서 재배하여 얻은 주요 식물학적 특성, 식미관련 물성검정, 영양가 분석 및 식미 평가에 대한 결과는 다음과 같다. 1. 공시된 찰옥수수 15개 교잡종에 대한 간장은 CNU08H-h39에서 235.7 cm, CNU08H-15에서 182.3 cm 범위로 공시종간에 큰 변이를 보였으며, 착수고 역시 Daehakchal Gold 1에서 83.7 cm, CNU08H-15에서 35.3 cm로 큰 차이를 보였다. 2. 이삭길이는 공시종 중에서 CNU08H-h121이 24.1 cm로 가장 길었고, CNU08H-71이 12.9 cm포 가장 작았으며 이삭직경은 Daehakehal Gold 1이 46.8 mm로 가장 굵고 CNU08H-69에서 26.1 mm로 가장 얇았다. 3. 공시종의 평균 당도는 15brix로 나타났는데 특히 CNU08H-15, CNU08H-35, CNU08H-h39, CNU08H-h102의 교잡종이 16 brix로 높은 편이었고 CNU08H-39에서 13 brix으로 가장 낮게 나타났다. 과피는 대조구인 연농찰이 $46.0{\mu}m$로 가장 두꺼웠고 CNU08H-39가 $23.0{\mu}m$로 가장 얇았다. 4. 생체이삭 내 단백질 함량은 대조구인 Ilmichal이 13.6%으로 가장 높게 나타났고, CNU08H-39가 8.6%으로 가장 낮았다. 아밀로펙틴 함량은 CNU08H-15의 교잡종이 94.5%로 가장 높았고 CaNU08H-71 에서 90.5%로 가장 낮았다. 5. 공시종에 대한 관능 평가 결과 대학찰골드 1호, CNU08H-h121 그리고 CNU08H-39순으로 높게 나타났으며 대조구인 연농찰 역시 비교적 높게 나타났다.

This study was carried out to compare botanical characteristics, physicochemical properties related to table quality and feed values and develop a new variety among 12 developed waxy com hybrids. These materials were produced in 2008 and cultivated in 2009 at Com Breeding and Genetics Farm of Coll. of Agri. & Life Sci., Chungnam Nat'l Univ. Botanical characteristics of used waxy com hybrids showed large difference among hybrids; stem height, ear height and ear length. In physical properties, range of kernel sugar content among used hybrids appeared 16.1 to 13.0brix(%). CNU08H-15, CNU08H-35 and CNU08H-h39 among these were highly appeared as 15 above and pericarp thickness of Yeonongchal was very thick as $46.0{\mu}m$, while CNU08H-39 among hybrids showed the thinnest as $23.0{\mu}m$ compared to other hybrids. Protein content as a indicator of table quality was the highest in Ilmichal among hybrids, while that of CNU08H-39 was the lowest, while amylopectin content was the highest as 94.5%, From experimental results, Daehakchal Gold 1, CNU08H-h121 and CNU08H-39 including check Yeonyoungchal were highly evaluated as new hybrid in thinner pericarp, high amylopectin and chewiness.
