摘要: 兰科植物为单子叶植物中最大的一个科。全国各地极其重视资源的调查、收集与驯化及其外来品种的引进;已有17个种的兰花种子成功运用超低温技术贮存;染色体分析技术及分子标记成为资源评价的重要手段,应用于研究兰科植物的亲缘关系及其遗传多样性这两方面的研究报道较多。兰花育种以传统的人工杂交为主,通过人工杂交已获得大量种间、属间杂交种;多倍体育种方法及生物技术作为辅助手段应用于兰花育种,获得了多倍体植株及转基因植株。

Abstract: Orchidaceae is one of the largest families of monocot plants. Germplasm resources investigation, collecting and domestication have been attached importance to by all over the country. The seeds of seventeen species of orchids have been stored successfully through cryopreservation. Chromosome techniques and molecular marker techniques have been demonstrated to be powerful techniques for the study of the estimation of resources. There are a few reports about the study of genomic analysis and genetic diversities of orchidaceous plants. Hand pollination is one of the most important ways of breeding and many hybrids have been attained. The techniques of polyploid breeding and molecular marker are helpful for breeding and polyploid plants and transgenic plants have been obtained.
