在国家863计划支持下,我国植物细胞工程育种技术取得新突破,开辟了细胞工程育种与常规育种技术相结合的新途径,加快了育种进程。(1)小麦及禾谷类体细胞杂交技术创新获得国际首创性成果。获得作物的小片段易位系是植物育种学家们长期追求的目标,其主要优点在于：小片段易位可在最大程度上排除 With the support of the National 863 Program, new breakthroughs have been made in the breeding of plant cell engineering in China, opening up new ways of combining cell-based breeding with conventional breeding techniques and speeding up the breeding process. (1) Innovations in wheat and cereal somatic hybridization won the first international achievements. The small advantage of crop translocation is a long sought after goal by plant breeders, with the main advantage that small fragment translocations can be eliminated to the greatest extent
