This experiment was carryed out in order examine the genetic telationships between the leaf and fruit characters by means of biometric genetics. 6 cultivars of the apple including a total of 18 trees were tested for the experiment. The results obtained can be summariged as follows; 1. Significant differences were observed among the mean values and the coeficients of variation, of the varieties for each charcter of leaf and fruit. In the ranges of the coefficients of the variation. leaf areawas the largest by 11% and leaf shape index was the lowest by 3.3% in leaf characters. Fruit stem length is the largest by 9.2% and fruit width was he lowest by 2.0% in fruit charcters. 2. The bread sense heritabilities of the leaf and fruit characters were relatively high, In leaf characters, petiole weight was the highest by 93% and leaf thickness was the lowest by 95.2% and fruit etem length was he lowest by 73.7% 3. As for genetic coefficient of variations, leaf weight was the highest by 37% in leaf characters. Fruit weight was the highest by 33.9% and fruit shape index was the lowest by 4.4% in fruit characters. Gemitic coefficients of variation was inclined to be higher than coefficients of variation. 4. In correlations between leaf characters and fruit characters, significant phenotypic correlation between petiole weight and fruit characters was noted. In correlations between leaf characters, and between fruit characters, high ignificant phenotypic correlations were observed. In general genotypic correlations were higher than phenotypic ones and environmental correlations wfre much changeabie 5. Leaf character which had the largest direct impact on fruit characters was the petiole diameter and petiole weight, in turm. But blade length, blade width and leaf shape index connected with leaf size were likely to be relatively large.
