Abstract

This study was carried out to compare a yield performance about CNU maize hybrids developed at the Maize Genetics and Breeding Lab. in Chungnam National University. Among the hybrids incorporated in the test, CNU 3 and 1 showed higher dry matter per 10a and lower kernel yield per 10a than check hybrid, Kwanganok. Hongchon 5 and Suwon169 showed higher kernel yield than Kwanganok. The average yield of CNU 3 hybrid in dry matter and CNU 4 in kernel yield were 2,106kg/10a and 854kg/10a in regional adaptability test, which were increased 33% and 8% compared with a check hybrid, respectively. Also, these hybrids had better stay green characteristics than check hybrid and showed moderately resistance to corn borer and leaf spot.

국내에서 새로 육성된 사료용 옥수수 교잡종에 대한 수량 관련시험을 실시한 결과 CNU 교잡종의 생육 특성은 다른 교잡종보다 간장과 착수고가 다소 낮은 경향을 보인 반면에, 종실 수량은 대조구인 광안옥에 비해 8%, 건물수량은 30%가 각각 증수되었으나 수원 169호보다 4%나 낮았다. 내재해성은 조명나방, 깨시무늬병에서 대조구와 비슷한 저항성을 보였으며, CNU교잡종의 후기 녹체성은 수원에서 육성된 교잡종과 같이 대조구 보다 우수한 것으로 나타났다.
