The Group Standard "Technical Code of Practice for Crossbreeding of Primulina (Gesneriaceae)" was promulgated and implemented


The group standard "Technical regulations for Hybrid breeding of Primulina Hance (Gesneriaceae)" (T/GXAS290-2022), which compiled by National Gesneriaceae Germplasm Resources Bank of GXIB, Gesneriad Committee of China Wild Plant Conservation Association and Gesneriad Conservation Center of China, was issued by Guangxi Association for Standardization. It has gone through many rounds of soliciting opinions and organizing experts to demonstrate and evaluate, and was officially uploaded to the national group standard information platform a few days ago. It is understood that this is the first group standard in Guangxi in the field of specialized research on Gesneriaceae in the horticulture. The standard was issued on April 15 and was implemented since April 21.

The supporting institute of National Gesneriaceae Germplasm Resources Bank of GXIB, Gesneriad Committee of China Wild Plant Conservation Association and Gesneriad Conservation Center of China, Guangxi Institute of Botany, Guangxi Zhuang Autonomous Region and Chinese Academy of Science, is the only institute drafting the standard of this group standard. In early April this year, after nearly seven months of internal and external (Guangxi) research, compilation and drafting, network soliciting opinions, expert group argumentation, expert consultation and exchange meetings, and other preliminary work, the expert team held a standard review meeting in Nanning and approved the final draft.

The standard defines the procedure of cross breeding of Primulina Hance (Gesneriaceae) and prescribes the operation instructions of breeding objectives, selection and matching of parents, hybridization, hybrid fruit harvest and seed treatment, hybrid seedling cultivation, character observation and screening, etc., and is suitable for interspecific and inter-variety cross breeding within the genus of Gesneriaceae in Guangxi.

Combined with the advantages of natural conditions and endemic plant resources in Guangxi, fully tap the potential of wild flower resources in our region, cultivating famous, special and excellent new varieties with local characteristics and independent intellectual property rights is of great significance to promote the development of characteristic flower seedling industry in Guangxi and promote the revitalization of rural areas in an all-round way. As a "new flower", Gesneriaceae is being attracted more and more attention in recent years. In 2020, Primulina Hance was listed in the new variety protection list of National Forestry and Grassland Administration of China for the first time. "National Gesneriaceae Germplasm Resources Bank of GXIB", "Gesneriad Committee of China Wild Plant Conservation Association" and "Gesneriad Conservation Center of China" rank first in the collection of Primulina (Gesneriaceae) germplasm resources in the world (231 species are known in the world, we have collected 203 species, accounting for 88%), which is in the leading level in terms of germplasm resources innovation in China. The development, publication and implementation of this standard will be of great significance for promoting the transformation of the characteristic resources of Primulina from resource-based utilization to sustainable utilization in our region.
