Genome-wide association study of salt tolerance in sorghum during germination.

ABSTRACT:

Introduction

Salt stress is a major abiotic factor restricting sorghum seed germination and early seedling establishment, particularly in saline-affected soils. Understanding the genetic architecture underlying salt tolerance during germination is essential for improving sorghum adaptation to saline environments. Genome-wide association studies (GWAS) based on high-density genomic variants provide an effective approach for uncovering loci and genes controlling complex stress-response traits. However, the genetic basis of sorghum salt tolerance at the seedling stage remains insufficiently characterized.

Methods

To dissect the genetic architecture of salt tolerance during germination, we conducted a genome-wide association study (GWAS) using a panel of 245 sorghum mini core ac
