六倍体欧洲李（Prunus arctica L.）是最重要的温带水果作物之一。其起源尚不清楚，因为野生形式失踪。可用于育种的遗传基础是高度多样的，为进一步改良果树提供了良好的基础。关于单一性状遗传的信息很少。育种的重点是抗性和果实质量。经典育种是最重要的方法。关于基因组序列的数据非常少。没有可用的标记辅助选择系统。基因工程仅限于转化种子中的胚胎组织。李是唯一的李属物种的基因型完全抗李痘病毒存在。这种抗性是基于植物细胞对病毒的过敏反应。种间杂交对于将欧洲李的抗性性状转移到近缘种和培育具有新果实性状的杂种具有重要意义。经典育种远不是李基因型改良的极限。_____________________________________________________________________________________________________________
The hexaploid European plum (Prunus domestica L.) is one of the most important temperate fruit crops. Its origin is unclear as wild forms are missing. The genetic base which can be used for breeding is highly diverse and provides a good base for further improvement of the fruit crop. Information on the inheritance of single traits are rarely available. Breeding focuses on resistance and fruit quality. Classical breeding is the most important method applied. Very few data is available on the genome sequence. No marker assisted selection systems are available. Genetic engineering is limited to the transformation of embryonic tissue derived from seeds. Prunus domestica is the only Prunus species where genotypes completely resistant to the Plum pox virus exist. This resistance is based on a hypersensitive response of the plant cells to the virus. Interspecific hybridization becomes more important in terms of transferring resistance traits from European plum to related species and of developing hybrids with new fruit characters. Classical breeding is far from being the limit of the improvement of plum genotypes. _____________________________________________________________________________________________________________
