Oleaster-leafed pear (Pyrus elaeagrifolia Pall. subsp. elaeagrifolia) fruits are used for food and dietary supplements in Turkey, and seedlings are used as rootstock for pear cultivars. Information on the effect of genotypes on oleaster-leafed pear fruit characteristics is needed in order to optimize production of quality food and dietary supplements. The characteristics of oleaster-leafed pear fruits relative to genetic background were evaluated from 16 wild grown oleaster-leafed pear genotypes at eastern Turkey. Genotype influenced ripening dates, fruit weight, fruit length/width ratio, fruit pedicel length, fruit flesh texture, fruit firmness, the number of seeds per fruit, soluble solid content, titratable acidity, total phenolic content, total flavonoid content and antioxidant activity. Analysis of the data obtained from 16 oleaster-leafed pear genotypes demonstrated a highly significant influence of genotype on fruit characteristics. The genotypes G12, G13 and G9 had the highest fruit weight (19.22, 18.54 and 18.30 g) and G9 the highest total phenolic content (122 mg gallic acid equivalent/100 g fresh fruit). The genotypes G3, G5, G11 and G13 had the slightly sandy fruit flesh texture and those genotypes may be good selections for processing and producing health oleaster-leafed pear products.

土耳其背竹叶梨（Pyrus elaeagrifolia Pall。subsp。elaeagrifolia）果实的特征

胡颓子，叶梨（梨elaeagrifolia鲍尔。亚种。elaeagrifolia）水果在土耳其用作食品和膳食补充剂，而秧苗则用作梨品种的砧木。为了优化优质食品和膳食补充剂的生产，需要有关基因型对oleaster-leafed梨果实特性的影响的信息。从土耳其东部的16种野生生长的梨叶生梨基因型中评估了梨叶生梨果实相对于遗传背景的特征。基因型影响成熟日期，果实重量，果实长宽比，果实花梗长度，果肉质地，果实硬度，每个果实的种子数，可溶性固形物含量，可滴定的酸度，总酚含量，总黄酮含量和抗氧化活性。对从16种橄榄酸浸过的梨的基因型获得的数据进行的分析表明，基因型对果实特性的影响非常显着。基因型G12，G13和G9的果实重量最高（19.22、18.54和18.30 g），而G9的总酚含量最高（122 mg没食子酸当量/ 100 g新鲜水果）。基因型G3，G5，G11和G13具有略带沙质的果肉质地，这些基因型可能是加工和生产保健橄榄叶梨产品的良好选择。
