Abstract:In order to develop and utilize germplasm resources of zingiberaceae flowers, 84 species of germplasm resources of zingiberaceae flowers were collected and introduced, analyzed and evaluated in combination with growth, ornamental characteristics and economic use, and germplasm innovation was carried out by artificial cross breeding. The results showed that 77 of 84 introduction germplasm resources of Zingiberaceae survived with survival of 91.7%, flowering rate of 98.7%, and fruiting rate of 63.6%. Among all species, 59.5% had excellent growth, 7.1% had good growth, 25% had moderate growth and 8.3% had died. Most species of Zingiberaceae originally distributed in tropical and subtropical areas at middle and low altitudes could be preserved in Guangdong-Hong Kong-Macao Greater Bay Area, while those in tropics at middle and high altitudes and special habitats areas were not suitable. Stage domestication method could be used for introduction and preservation, and there were 60.7% species of multipurpose flowers. The hybrid breeding could not only innovate new germplasm, but also transfer and preserve superior genes of Zingiberaceae flowers.
