Screening wheat genotypes in alkaline sodic subsoil locations
Aims

This paper presents results from a genotype screening experiment conducted in 2019 at Grogan in southern NSW for identifying wheat
genotypes and traits linked to sodicity tolerance under field conditions with subsoil sodicity.

Key messages

• Genotypic variability observed in response to wheat grain yield in alkaline sodic subsoil.
• MaceA, CorackA, ScepterA and Emu RockA were the top performing cultivars over three consecutive years.
• Higher grain yield was attributed to greater subsoil water extraction and capacity to maintain higher harvest index under drought conditions.
