Description This dataset provides a comprehensive agro-morphological, physiological, and biochemical characterization of the wild tea (Camellia sinensis) genotype TS567LVC collected from Phu Yen Province, Vietnam, and evaluated under controlled field conditions. It supports the study: “Agro-Morphological Evaluation and Conservation Potential of the Wild Tea (Camellia sinensis) Genotype TS567LVC from Phu Yen, Vietnam” . The dataset includes high-quality experimental data derived from a randomized complete block design (RCBD) with replicated measurements across three tea genotypes: TS567LVC (wild genotype), a Lam Dong landrace, and the commercial Oolong cultivar Kim Tuyen. All genotypes were cultivated under uniform agroecological conditions in Sông Cầu district (13°40′36″N, 109°12′29″E; 480 m a.s.l.) without supplemental irrigation, simulating low-input farming systems. The dataset consists of the following components: Raw trait data: Replicated measurements (n = 5 per genotype) of key agro-morphological and physiological traits, including plant height (cm), leaf area (cm²), relative water content (RWC, %), chlorophyll index (SPAD), and total polyphenol content (mg g⁻¹ dry weight). Processed statistical data: Summary statistics (mean values) and ANOVA results (p-values) for all measured traits, enabling direct comparison among genotypes. Environmental data: Site-specific agroecological parameters, including geographic coordinates, elevation, annual rainfall (~1600 mm), temperature range (22–26°C), and soil characteristics (Ferralsol, pH 5.0–5.5). Metadata and documentation: A complete data dictionary, structured metadata, and README file ensuring transparency, reproducibility, and compliance with FAIR data principles. Reproducibility resources: An analysis script (R) for performing statistical analysis and replicating ANOVA results. The dataset reveals significant differences among genotypes in all measured traits, with TS567LVC demonstrating superior drought tolerance (RWC ≈ 89%), higher chlorophyll content (SPAD ≈ 42.7), and elevated polyphenol concentration (≈ 29.5 mg g⁻¹), indicating strong adaptive capacity and high-quality potential. These results highlight the importance of wild tea genetic resources as reservoirs for climate-resilient breeding and sustainable tea production. This dataset is suitable for a wide range of applications, including: Agro-morphological and physiological trait analysis Comparative evaluation of tea genotypes Climate resilience and drought tolerance studies Biochemical quality assessment in tea Conservation and breeding of plant genetic resources Geographic coverage: Phu Yen Province, VietnamTemporal coverage: 2022–2024 (field experiment period)Data format: CSV, JSON, R scriptLicense: CC-BY-4.0 By providing structured, reproducible, and high-resolution experimental data, this dataset contributes to the conservation and utilization of underexplored wild tea germplasm and supports future research in sustainable and climate-resilient tea systems.
