Understanding the genetics of root system architecture in pigeonpea [Cajanus cajan (L.) Millsp.].

ABSTRACT:

Key message

Field-based phenotyping of root system architectural (RSA) traits in a diversity panel (PI-GAP) of pigeonpea was conducted across three diverse pigeonpea growing environments along with identification of genomic regions associated with these traits through GWAS analysis. Root system architecture (RSA) plays a crucial role in plant stress tolerance mechanisms serving as the main route for water and nutrient acquisition, while also mediating plant-rhizosphere signalling. In the current study, an attempt was made to understand the genetic variability and genomic regions associated with RSA traits, as a relatively unexplored area of research in pigeonpea. The field-based "Shovelomics" approach was utilized to phenotype eight RSA traits: tap root length (TRL), lateral root l
