Overview

Randomized trial shows associations between SSR markers and yield traits in soybean germplasm, indicating useful genetic diversity for breeding.

Key Points

  • This research aims to explore genetic diversity and its relationship with yield traits in soybean using SSR markers.
  • Analyzed 150 soybean accessions with 20 pairs of SSR primers under two environmental conditions.
  • Conducted genetic diversity analysis on 12 agronomic traits and cluster analysis of the accessions.
  • Performed association analysis between SSR markers and yield-related traits using GLM and MLM.
  • Identified 44 SSR markers significantly associated with yield-related traits, with 13 markers linked to multiple traits.
  • The study showed high genetic diversity with an average polymorphism rate of 96%.
  • Cluster analysis categorized accessions into distinct groups based on their genetic traits.
