“…The development of molecular markers had also facilitated research on the origin and evolution of tea plants, breeding and refinement processes. So far, various markers have been developed and applied in tea plants, such as random amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) markers to analyze the degree of genetic diversity and population genetic structure in tea clones and to select superior varieties for the further hybrid breeding materials of tea plants [ 107 ]. The development of expressed sequence tag-simple sequence repeat (EST-SSR) markers in tea oil plants could be applied for the identification of tea oil varieties and protection of genetic resources [ 108 ].…”

Tea plants are an economically important crop and conducting research on tea breeding contributes to enhancing the yield and quality of tea leaves as well as breeding traits that satisfy the requirements of the public. This study reviews the current status of tea plants germplasm resources and their utilization, which has provided genetic material for the application of multi-omics, including genomics and transcriptomics in breeding. Various molecular markers for breeding were designed based on multi-omics, and available approaches in the direction of high yield, quality and resistance in tea plants breeding are proposed. Additionally, future breeding of tea plants based on single-cellomics, pangenomics, plant–microbe interactions and epigenetics are proposed and provided as references. This study aims to provide inspiration and guidance for advancing the development of genetic breeding in tea plants, as well as providing implications for breeding research in other crops.

“…An array of molecular marker technologies has made substantial contributions to the discrimination of plant varieties, assessment of genetic diversity and relationship, and construction of genetic maps (L. Chen et al., 2005, 2007; P. J. Wang, Fang et al., 2022). Notably, RAPD (random‐amplified polymorphic DNA), amplified fragment length polymorphism, inter simple sequence repeat, and simple sequence repeat markers have been widely applied to tea plants (Barut et al., 2020; Fang et al., 2012; Jose et al., 2022; Sharma et al., 2022), effectively enabling the evaluation of genetic diversity of tea germplasm resources. As a third‐generation molecular marker technology, single nucleotide polymorphism (SNP) stands out as a biomarker of choice for its wide distribution in plant genomes (Buckler & Thornsberry, 2002; Fang et al., 2014).…”

Ningde, (ND) situated in China's prominent tea‐producing region, is recognized as the origin of white tea. It also boasts a wealth of premium tea germplasm resources, which are of vital importance in tea breeding programs. In this investigation, utilizing nanofluidic single nucleotide polymorphisms (SNP) genotyping technology, the genetic diversity and population structure of tea germplasms sourced from ND and its surrounding regions were scrutinized. A comprehensive collection of 101 tea plant germplasm accessions sourced from ND and its neighboring regions was acquired. Our analysis identified 75 stable and reliable SNP loci that demonstrated the rich genetic diversity of the ND tea germplasms, with an average observed heterozygosity (Ho) of 0.411 and expected heterozygosity of 0.382. Notably, the multiple analyses based on high‐quality SNPs revealed that the wild‐type landraces of tea plants in ND are genetically distinct from the cultivars. The analysis of molecular variance results suggested that intrapopulation variation contributed to 79% of the total genetic variation. Moreover, tea plant germplasms in ND interacted with the genetic material of landraces in Nanping and Lishui. Overall, our study provides essential insights into the genetic diversity, relationship, and conservation of ND tea germplasms, and lays a molecular basis for innovative utilization and breeding improvement of tea plant germplasms.This article is protected by copyright.
