This study was carried out to determine the relationships between fruit weight, fruit length, fruit flesh weight, red seed coat weight per fruit, seed weight per fruit and number of seeds per fruit in bitter melon plant. The study was carried out in field conditions in Rize for 2 years. Seedlings grown in viols were planted in trial plots at a distance of 70x50 cm at the period of 4-5 leaves. The fruits were harvested every two days when they reached maximum weight and turned orange. A total of 10 fruit harvests were made in August and the harvest was completed in 18 days. The share of harvested fruits in the total product ranged from 5.2% to 14.9%. The lowest share occured on the first harvest day while the highest share was realized in the 7th Harvest. 52% of the total product was reached on the 6th harvest day. The data showed that the variation in average fruit weight depending on the harvest time in the 18-day harvest period was not statistically significant. The results contain important data regarding the distribution of the harvested fruits in terms of weight within the harvest period. During the harvest, the planned measurements were made on a total of 20 fruits randomly selected from among the fruits taken from 20 plants, and the average values of some fruit characteristics were determined and the relationships between these traits were clearly revealed. When evaluated over 2-years averages; fruit weight, 92.2±19.2 g; fruit length, 14.4±1.7 cm; fruit flesh weight, 73.0±14.8 g; red seed coat weight per fruit, 13.8±3.9 g; number of seeds per fruit, 21.9±5.7 pieces; seed weight per fruit was determined as 4.65±1.3 g. According to the results of the correlation analysis, the trait showing the highest correlation with fruit weight was the fruit flesh weight (r=0.989, P <0.01) and followed by seed weight per fruit (r=0.917, P<0.01), number of seeds per fruit (r=0.871, P<0.01), P<0.01), red seed cover weight (r=0.816, P<0.01) and fruit length (r=0.707, P<0.01) respectively.
