[Comprehensive evaluation of Pinellia ternata germplasm resources based on phenotypic trait classification]

Area of Science:

• Agricultural Science
• Botany
• Pharmacognosy

Context:

• Germplasm resource evaluation is crucial for developing, utilizing, and conserving Chinese medicinal plants.
• Pinellia ternata breeding and production rely on selecting excellent germplasm.

Purpose:

• To analyze population diversity and identify superior germplasm resources of Pinellia ternata.
• To provide a foundation for genetic resource excavation and new variety breeding.

Summary:

• Evaluated 21 Pinellia ternata germplasms from major Chinese production areas using phenotypic and quantitative trait analysis.
• Identified significant phenotypic variation, with adenosine content showing the highest coefficient of variation.
• Cluster and principal component analyses classified germplasms, highlighting BX007, BX008, and BX005 for high yield and uridine content.

Impact:

• Identified nine key traits for comprehensive germplasm evaluation.
• BX007 identified as a potential high-yield, high-uridine content variety.
• Provides a systematic evaluation framework for Pinellia ternata genetic resource development.
