This study was about the effect of different pollen pollination on fruit quality of ‘Cuiguan’ pear at harvest date and cold storage period. At Songjiang District in Shanghai, China, the main cultivated ‘Cuiguan’ pear was hand pollinated with 6 pollen treatments (i.e.,‘Qingxiang’ pear, ‘Zaoshengxinshui’ pear, ‘Housui’ pear, ‘Wohwang’ pear, ‘Huanghua’ pear, and mixed varieties pear). Morphological parameters of fruit (fruit shape index, weight, seed number, and skin color) and quality parameters (soluble solids content, titratable acid content, firmness with peel and firmness without peel) were investigated at harvest time and during cold storage to identify the different pollens pollination effect. ‘Cuiguan’ pear fruits obtained from pollination with ‘Huanghua’ pear and ‘Wohwang’ pear recorded good appearance parameters (fruit shape index, weight, and skin color) and fresh quality (soluble solids content, titratable acid content, and palate). Among the ‘Cuiguan’ pear fruits with 6 pollen treatments, ‘Huanghua’ resulted in the largest fruits with the highest soluble solids and titratable acid contents, and ‘Wohwang’ resulted in the best cold storage quality with the highest soluble solids and titratable acid contents. This study provided a basis for the selection of pollinating pear varieties and quality improvement of ‘Cuiguan’pear in Shanghai.
