Randomized trial assesses yield traits in soybean germplasm, suggesting markers for climate resilience.

This research aims to identify genetic markers linked to yield traits in soybean during the spring season.
Screened 100 soybean accessions across variable planting dates in 2020 and 2021
Conducted genome-wide association study using 42,449 SNPs from SoySNP50K array
Analyzed phenotypic data of six yield-related traits such as plant height and yield per plant.
Identified 77 significant marker trait associations with traits linked to plant height and yield per plant.
Major allele frequency, genetic diversity, and polymorphic information content were 0.78, 0.28, and 0.28, respectively.
Seven SNPs linked to multiple traits were found on chromosomes associated with thermotolerance and other yield traits.

Ghuman et al. (2026) studied this question.
