These studies were conducted to obtain basic information on breeding for high leaf yield of perilla. A half diallel set of six parents was grown in a randomized complete block design with two replications. The genetic variance component and heritability of quantitative characters related to leaf yield were estimated. Overdominance was observed for plant height and leaf size, complete dominance for the number of internodes on the mainstem, and partial dominance for days to flower, the number of leaves per plant, total leaf area per plant, dry weight of leaves per plant and stem diameter. Direction of dominance was negative for days to flower, whereas it was positive for other characters. The number of effective gene groups was estimated as one for days to flower and total leaf area per plant, three for the number of leaves per plant, three or four for dry weight of leaves per plant, and four or five for stem diameter and plant height. Estimated heritability in the narrow sence was low for plant height and leaf size, whereas it was high for other characters. Estimated heritability in the broad sense was also high for all characters
