A novel P indicator to evaluate bread wheat (Triticum aestivum) genotypes to identify tolerance to phosphorus deficiency based on two distinct root phenotyping platforms.

ABSTRACT:

Background and aims

Phosphorus (P) is a crucial macronutrient for plant growth that, despite its abundance in soils, is often a limiting factor in agricultural productivity, particularly for cereals such as wheat. In this study, the response of different wheat genotypes to two different levels of P was evaluated in a large trial encompassing 26 genotypes using two distinct root phenotyping platforms, ALSIA and 4PMI.

Methods

Rhizotubes allowed non-invasive root phenotyping, revealing significant genotypic effects on biomass production and root system traits. Phosphorus acquisition and use efficiency of the wheat genotypes were estimated by using five different metrics.

Key results

A synthetic indicator for agronomic relevance integrating the efficiency metrics was esta
