Abstract

This study was carried out to find a new corn cultivar with multiple tillers that is suitable for forage. Materials were developed at the Corn Breeding Laboratory of Chungnam National University. A total of 3,650 accessions were collected domestically and from other countries, including China. Among them, 16 CNU inbreds, tillering and non-tillering, were compared to each other in terms of stem heigh, number of tillers, fresh weight, and dry weight per plant. Of these surveyed traits, the stem heigh at tasseling stage was 140~190 cm and number of tillers per plant ranged from two to four. Fresh weight and dry weight of these lines were higher in the tillered than in the non-tillered sample.

국내 옥수수 유전자원 중에서 분얼이 많고 생육이 우수한 계통을 이용하여 생육특성 및 건물수량을 조사한 결과는 다음과 같다. 1. 육성된 계통의 평균 간장은 174.7 cm, 개화소요일수는 61일, 주당분얼수는 2.3개, 착수고는 64.1 cm로 나타났다. 2. 평균 도복율은 2정도로 모든 계통에서 내도복성을 가졌다. 3. 주당 평균 이삭중은 135.9 g으로 CNUB14T-01에서 249.0 g으로 가장 높았다. 4. 공시계통의 주당 평균 생체중과 건물중은 각각 694.4 g과 183.7 g으로 나타났으며, 평균 건조 비율은 30%로 나타났다. 5. 공시계통 중에서 CNUA14T-07의 생체중과 건물중이 2367.8 g과 532.8 g으로 가장 높게 나타났다.
