영문 초록

Six corn inbreds and 15 F₁ among their were used to study the combining ability and genetic analysis of leaf area components in corn(Zea mays L.). GCA(general combining ability) was more important than SCA(specific combining ability) in LN(leaf no.), TL(total leaf length) and MW(mean leaf width). Ga 209 showed the highest GCA effects in LN, TL, TW(total leaf width), TLA(total leaf area) and LAI, while B84 showed the lowest GCA effects in LN, TLA and LAI. The F₁ between KS15 × Va35 showed the highest SCA effects in TL,TLA,ML,MW, MLA and LAI, and the F₁ between KS8 × B68 showed the lowest in all characters. Partial dominance was exhibited by LN, and over dominance was exhibited by TL, TW, TLA, ML, MW, MLA and LAI. Among 6 inbreds, Ga 209 had the most dominant genes for all characters, while Va 35 had the most recessive genes for all characters.
