옥수수 이면교잡에 의한 등숙기간의 유전 분석
Inheritance of Grain Filling Duration in Corn
초록
옥수수의 숙기가 서로다른 8개의 자식계통과 이들간의 이면교배에 의하여 생산된 28개
This study was conducted to clarify the genetic effect on the duration of grain filling with using the eight corn inbreds. In diallel cross analysis, the grain filling during the lag period showed partial dominance with great additive effects. Inbreds FR14A and A508 showed greater recessive gene effects for lag period, while FR25 showed greater effects of dominant genes. The genetic analysis for the effective filling period(EFP) showed over dominance without additive gene effects. FR25 of 8 inbreds showed greatest effects of dominant genes for EFP, while YUBC208 showed greater recessive gene effects for EFP than other inbreds. The genetic analysis for total grain filling period(TGFP) seemed to be due to partial dominance with greater additive effects. Early inbred line, YUBC208 especially showed greater recessive gene effects for TGFP than others. No. of effective genes related to EFP and TGFP were estimated by at least 5.
