黑龙江22个栽培苹果品种选育系谱分析

Pedigree Analysis of 22 Apple Varieties Breeding in Heilongjiang Province

  • 摘要: 以黑龙江省栽培的22个育成苹果品种为材料,对其经济性状及其亲本组成和选配特点进行了分析,并绘制了22个苹果品种的系谱图。结果表明,22个苹果品种中亲本来源明确的有20个,其中杂交选育品种18个,占90%。根据黑龙江省的气候特点和品种特性分析,育成品种以晚熟(54.6%)为主g均为盖色红色、抗寒品种;明确记载的耐贮藏品种有12个(54.5%),果实以小果(63.6%)为主。分析亲本来源明确的20个品种发现,直接亲本和原始亲本的主要类型均为引进品种。系谱分析发现,骨干亲本为“金冠”“铃铛果”“大秋”。综上所述,黑龙江栽培的育成苹果品种以杂交选育为主,晚熟、抗寒、耐贮、小果为主要特性,亲本组配时性状优良或与育种目标相似的亲本组合更容易选育出抗寒优良品种。

     

    Abstract: The economic characters, parental composition and matching characteristics of 22 cultivated apple cultivars in Heilongjiang Province were analyzed, and the pedigree maps of 22 cultivars were drawn. The results showed that 20 of the 22 apple varieties had clear parental origin, and 18 of them were crossbred, accounting for 90%. According to the climatic characteristics and variety characteristics of Heilongjiang Province, the cultivated varieties were mainly late maturing(54.6%), all of which were red and cold resistant varieties. There were 12 varieties(54.5%) that could withstand storage, and the fruits were mainly small fruits(63.6%). Analysis of 20 varieties with clear parental origin showed that the main types of direct parents and original parents were introduced varieties. Genealogical analysis found that the backbone parents were ’Jinguan’, ’Jingguo’ and ’Daqiu’. To sum up, the cultivated apple varieties in Heilongjiang were mainly hybridization and breeding, with late ripening, cold resistance, storage resistance and small fruit as the main characteristics, and the parent combinations with good traits or similar breeding objectives were more likely to breed excellent cold resistance varieties.
