摘要
自20世纪60年代黑龙江省开始梨育种研究以来,共审定推广主栽梨品种18个,这些优良新品种在当地梨生产中发挥了重要作用。通过对审定的18个梨品种选育系谱分析发现,有16个新品种是通过杂交育种育成,其中龙香梨作为黑龙江省梨育种的重要杂交亲本材料,直接利用其血缘育成新品种8个,其次是苹果梨,利用其血缘育成品种4个。进一步根据育种系谱划分亲缘关系,发现18个梨品种中除秋香梨、晚香梨和秋黄梨外,基本可以划分为2个类群,分别为苹果梨类群(Ⅰ)和龙香梨类群(Ⅱ)。植物学特性分析表明,黑龙江省梨品种成熟期较早,抗寒性强,各品种间果实品质差异明显。
A total of 18 varieties of pear were authorized and generalized in Heilongjiang province which begun pear breeding work after 1960s. It plays an important role in pear production in Heilongjiang province. Pedigree analysis of 18 varieties showed that 16 pear varieties were bred through hybridization. As an important hybrrial of Heilongjiang pear breeding,8 new varieties were breeding when Longxiang pear waAnd 4 new varieties were breeding when Pingguo pear was used. Furthermore,18 pear varieties were devidedpopulation such Pingguo pear population（ I ） and Longxiang pear population（ n ） based on pefor Qiuxiang pear, Wanxiang pear and Qiuhuang pear. The botanical traits analysis showed that pears of Hti- longjiang province had an early maturity and strong resistance to cold. There are significant difference in fruit and quality traits among these pears.
