Summary
High-throughput plant phenotyping (HTPP) advances crop breeding by automating trait measurement. This review explores HTPP methods to improve grapevine field phenotyping for diversity and stress tolerance, crucial for Vitis vinifera breeding programs.
Area of Science:
- Agronomy
- Plant Science
- Genetics
Background:
- Manual plant phenotyping is a bottleneck in crop breeding.
- High-throughput plant phenotyping (HTPP) uses automated imaging and data processing.
- Field phenotyping of grapevine presents significant challenges.
Purpose of the Study:
- To review current and potential methods for improving grapevine field phenotyping.
- To support the characterization of Vitis vinifera genetic diversity.
- To aid in selecting grapevine varieties resilient to abiotic stress.
Main Methods:
- Review of existing literature on plant phenotyping techniques.
- Discussion of imaging and automated data retrieval for HTPP.
- Analysis of field experimental design and data gathering methodologies.
Main Results:
- HTPP offers solutions to manual phenotyping bottlenecks.
- Field phenotyping challenges include environmental variability and scale.
- Specific traits and methodologies for grapevine selection are discussed.
Conclusions:
- Improved field phenotyping is essential for grapevine breeding.
- HTPP methods can enhance the characterization of grapevine diversity.
- Selection for abiotic stress tolerance in Vitis vinifera requires robust phenotyping strategies.
