Introduction

Crop improvement relies heavily on understanding the genetic basis of desirable traits. Phenotyping, the quantitative measurement of plant traits, plays a vital role in linking genotype to phenotype. Modern breeding programs require accurate, efficient, and high-throughput phenotyping methods to identify superior genotypes. This training course provides a comprehensive overview of phenotyping principles, techniques, and applications in crop breeding. Participants will learn about various phenotyping platforms, data analysis pipelines, and statistical methods for trait dissection. The course emphasizes hands-on experience with real-world datasets and software tools commonly used in crop phenomics. Furthermore, the course will cover the integration of phenotypic data with genomic information to accelerate breeding cycles and improve crop performance. The overall goal is to equip participants with the skills needed to design and implement effective phenotyping strategies in their own breeding programs.
