摘　　要：在介绍近年来植物嫁接杂交研究新进展的基础上,着重阐述了嫁接杂交与果树遗传特殊性的关系。砧木中的遗传物质转移并整合到接穗生殖细胞和胚胎细胞的染色体组中,是杂种后代出现大量野生植株和果树遗传不遵守孟德尔定律的主要原因。还讨论了嫁接杂交在果树育种中的重要意义。Emphatically discusses the relationship between graft hybridization and the specificity of heredity in fruit trees on the basis of introducing the recent achievements in plant graft hybridization.We propose that genetic materials in rootstock being translocated and integrated into the genome of the germ cells and embryonic cells in scion are the main reasons why the majority of the hybrid seedlings have wild properties and the heredity of fruit trees violate Mendel's laws of heredity.The potential of graft hybridization in fruit breeding are also discussed.
