摘　　要：为了提高苹果梨产品的优势,克服其弱点及提高梨树育种工作的研究水平,以‘苹果梨’为中心的7个杂交组合、228株实生树为试材,进行了各组合亲本和后代的性状分析,探讨了各主要性状的遗传趋势。结果表明,‘苹果梨’杂种后代可溶性固形物含量的遗传传递力平均为100.3%,趋近于亲中值。果实风味出现较高比例的是酸甜、甜酸和甜,‘苹果梨’与脆肉杂交后代中没有分离出软肉类型,‘苹果梨’与软肉类型杂交后代都以脆肉类型为主,‘苹果梨’杂种后代果汁含量较亲本有降低的趋势。因此,‘苹果梨’的优良果实经济性状遗传力较强,作为育种亲本,在北方梨新品种选育中具有广泛的应用前景。In order to improve the value of ＇ Pingguoli ＇ fruits,overcome the drawbacks and promote the breeding work of pear,the variant traits of hybrid seedlings from seven crosses taken ＇ Pingguoli ＇ pear as one paternal material were determined and genetic tendencies of major fruit traits were analyzed.The results showed that the heritability of soluble solid content in hybrid seedlings was 100.3% near to mid-parent value.The flavors of hybrid progenies appeared high proportion of sour-sweet,sweet-sour and sweet types.No soft-flesh progenies were found from crosses between ＇ Pingguoli ＇ pear and crisp pears and the majority of progenies crossed between ＇ Pingguoli ＇ pear and soft-flesh types bore crisp fruits.Compared to paternal parents,the progenies showed a decreasing tendency in the juice content.Thus,＇ Pingguoli ＇ pear showed high genetic tendency in the economic fruit traits and has a wide range of application in breeding of pear in northern China.
