Pollinizer Potentials of Reciprocally Crossed Summer Apple Varieties by Using ANOVA and Resampling Based MANOVA

Within the scope of this study, the compatibility of some summer apple cultivars and the possibility of their use as pollinator to each other were investigated. In addition, the effects of factors on quality parameters were investigated under different statistical models on harvested fruits. It can be said that a suitable and sufficient number of pollinators should be used since the initial fruit set was below 20% in all examined varieties except ‘Summer Red’ (22.24%). As a result of standardization of data, ‘Vista Bella’ for ‘Jersey Mac’ and ‘Jersey Mac’ for ‘Vista Bella’ were the most successful pollinators to obtain high quality fruits. A similar reciprocal effect was also seen between ‘Williams Pride’ and ‘Summer Red’. However, the fact that open pollination gave the best results showed that at least one more suitable pollinator should be used to the proposed cultivars. The xenia effect was seen in many characteristics including fruit width, fruit length, fruit weight, red blush ratio and seed weight. While the number of seeds and stalk length positively affected the pomological characteristics of the fruits, the increase in fruit size negatively affected the coloration. Multivariate methods gave interpretations that are more accurate in statistical analysis, since the interaction effects of factors on the characteristics investigated are important and the characteristics are related to each other.
