Implication

Genome-wide association studies identify candidate genes linked to biological nitrogen fixation in chickpea, suggesting pathways for marker-assisted breeding.

Key Points

This research aims to identify new sources of nodulating chickpea genotypes and the genomic regions controlling biological nitrogen fixation.
Evaluated a global germplasm collection of 284 chickpea genotypes for nodulation and yield traits in four different environments
Used genome-wide association studies to uncover marker-trait associations related to biological nitrogen fixation
Conducted correlation analysis to assess the relationship between nodulation traits and yield
Identified 65 and 109 significant marker-trait associations linked to number of nodules and nodule fresh weight, respectively
Notable candidate genes could be converted into KASP markers for marker-assisted breeding
The genotypes ICC 7390, ICC 15, ICC 8348, and ICC 2474 showed high rates of nodulation across locations
