Abstract:

Hybrid breeding is an important means to develop and utilize orchid resources. Renanthera plants have good hybridization affinity and often conduct inter-genus hybridization, which is also one of the important research materials for studying the hybridization barriers of distant plants. In this paper, the basic characteristics and distribution of plant resources of the Renanthera were briefly described, the cross breeding and cross combination of Renanthera and its related genera were summarized, and the problems such as the low rate of seedling regeneration and low level of molecular research were pointed out. Finally, we put forward some measures to promote the inter-genus breeding work, such as paying attention to the selection of parents, strengthening the basic breeding research, expanding the cross-breeding work among related genera, and increasing the in-depth research on the molecular level of inter-genus hybrids.

Key words: Renanthera, relative genus, intergeneric hybridization, parent selection, germplasm resources, molecular study
