Quality classification of 'Hayward' kiwifruit grown in Altınordu (Ordu, Türkiye) based on fruit weight

In this study, it was aimed to classify the 'Hayward' kiwifruit, whose production has increased rapidly in recent years in Türkiye and has adapted to the ecology of the Eastern Black Sea Region, in terms of quality according to fruit weight in Altınordu district, which is the highest production area of Ordu province (Türkiye). The research was designed according to the randomized block experimental design with 3 replications. Within the scope of the study, fruits harvested in 5 orchards in 3 selected neighborhoods in Altınordu District were classified in terms of quality according to TS 11306 standard, based on fruit weight. The harvested fruits were weighed one by one with a precision scale and classified as Extra (<90 g), First Class (70-89 g), Second Class (65-69 g). In addition, the total number of fruits per tree and discarded fruit rates were also determined. As a result, the total number of fruits per tree varied between 491-1265, the extra fruit rate varied between 31.09-92.52%, the 1st class fruit rate varied between 4.12-49.86%, the 2nd class fruit rate varied between 1.50-30.04% and the discarded fruit rate varied between 0.34-4.50%. The average values of these features were found to be 833.29, 70.47%, 19.28%, 8.32% and 1.78%, respectively. All examined features showed significant variation according to neighborhoods and orchards. In addition, a very significant negative correlation was determined between the extra fruit ratio with the 1st, 2nd class and discarded fruit ratios.
