영문 초록

The segregating frequency distribution of stay-green score and days to ear leaf senescence(DELS) from silking generally had a simple bi-modal pattern irrespective of planting dates and the pattern of stay-green score shifted to higher level with later stages. The Hi39/KS75 had the longest DELS and it showed highest stay-green characteristics at 67 days after silking(DAS). The KS75 was considered a useful material in breeding of stay-green lines. The distribution patterns of F₂ progenies of Ga209/Hi39 and Ga209/KS75 had highly characterized as related to stay-green at 37 DAS, but that of characteristics shifted to lower levels at 52 DAS, and maintained up to 83 DAS. In the progenies of the three crosses, F₂ from Hi39/KS75 showed high from early days after silking in stay-green score, DELS and number of fresh leaf. It was possible to obtain higher stay-green lines than those of parents in the cross of Hi39/KS75.
