Abstract

Stem height of the new developed "Daedekchals" waxy hybrids were higher than check hybrid, Chalok #1, while days to tasseling were delayed about four to seven days. Number of tillers per plant of the these new hybrids including check were appeared to be one less as non-effective tiller. Ear length and diameter of the new waxy hybrids were longer and thicker than check, respectively. In addition, pericarp thickness of the Daedekchal #1 and #2 among new developed waxy hybrids were thinner and sugar content were higher than check.

1. 새로 육성된 4개의 대덕찰 찰옥수수 교잡종에 대한 간장은 대조구인 찰옥 1호보다 큰 반면에 개화기는 약 4~7일 늦었으며, 모든 공시 교잡종의 주당 분얼수는 한 개이하의 무효분얼로 나타났다. 2. 새로 육성된 대덕찰옥수수의 이삭길이와 직경은 대조구인 찰옥 1호보다 크게 나타났으며, 특히 대덕찰옥수수 1호와 2호의 과피두께는 대조구보다 얇았고, 당도 역시 높게 나타나 우수 교잡종으로 평가되었다.
