Abstract
The primary aim of this study was to understand the cross-fertilization compatibility and the xenia effect of different pollens from different pollinizers in Prunus armeniaca Küzlük Ürük, and to screen the pollination combinations with high cross-fertilization compatibility and positive xenia effect by conducting a hybridization test of 14 local cultivars with Küzlük Ürük in Xinjiang.
The results showed that cross-fertilization of all 14 pollinizers increased fruit-set percentage of Küzlük Ürük, in which the cross compatibility of P. armeniaca Jaghda Maysam with Küzlük Ürük was the highest (fruit-set percentage 31.5%). Meanwhile, cross-fertilization of all 14 pollinizers effectively improved the physical characteristics of Küzlük Ürük fruit, but most of them showed a negative or less positive effect in enhancing the fruit biochemical characteristics, with a decline in the ascorbic acid content of the hybrid fruit of Küzlük Ürük. P. armeniaca Tarhan Ürük was found to be a more favorable candidate pollinizer for Küzlük Ürük for its higher cross-compatibility with Küzlük Ürük and positive effects on fruit size and quality of Küzlük Ürük.
