영문 초록

This study was conducted to determine the genetic nature of rindless culm(rlc) of the Dangin maize(Zea mays L.) line developed from Korean native lines. The materials used were 12 hybrids, including Dangjin/FR3019, reciprocal crossed between some local inbreds with Dangjin inbred tester, which shown a portion of internodes lacking rind longitudinally. All hybrids used were segregated into purple and green plants in the ratio of 3:1 in the F2. Accordingly, purple was assumed to be controlled by single domipnant gene. The rindless culm in F2 segregation of purple plant was controlled by single recessive gene. Correlation coefficients between purple plant and rindless culm, and between purple plant and stay green were very high as r=0.941 and r=0.88, respectively. Thus, these characteristics were assumed to be affected maternal effect. Using stay green gene for maize breeding in the fruture will be effective for developing better quality of silage crops.
