“…One of the most significant root traits, root biomass, is a fundamental trait linked to nutrient acquisition in wheat. Higher root biomass has been associated with an increased nutrient uptake capacity and improved grain yield in wheat genotypes (Gregory et al, 2013). This is supported by a previous study that demonstrated an increase in yield and nutrient use efficacy with root biomass and root length in wheat (Duncan et al, 2018).…”

Understanding the phenotypic variability in root system architecture and root-shoot relationships across different growth stages of wheat is of utmost importance for the improvement of genotypes with enhanced nutrient uptake and resource-use efficiency. This study focused on identifying variations and relationships in the root and shoot characteristics of seven modern cultivars and twelve ancient wheat accessions of different species, including T. monococcum, T. turanicum, T. polonicum, T. mirabile, T. durum, and T. aestivum, during the early vegetative growth and stem elongation stages. The results demonstrated significant phenotypic variation among the genotypes for shoot traits, root biomass, rooting depth, R/S ratio, and seminal and nodal root numbers. When considering both growth stages, the dry land-adapted cultivar ‘Taner’ and ancient wheat species, such as T. turanicum (2) and T. monococcum (1) accessions, exhibited deeper roots, which can enhance access to water in drought-prone areas. Furthermore, it was observed that modern wheat cultivars and T. turanicum accessions exhibited increased root biomass, suggesting a higher allocation of resources towards root growth, which could potentially enhance nutrient uptake. Conversely, T. monococcum accessions and T. mirabile revealed lower root biomass compared to other ancient species and modern cultivars. Additionally, the unrooted cluster analysis based on root biomass, rooting depth, and root to shoot ratio at both growth stages indicated a distinct separation of T. monococcum accessions and T. mirabile from other genotypes. Overall, these findings underscore the importance of phenotypic diversity in root traits for crop improvement and adaptation to varying environments. Identifying genotypes with desirable root characteristics can enhance nutrient and water uptake efficiencies, leading to increased crop productivity and sustainability.

“…Studies showed a direct relation between root biomass and P and K uptake in wheat ( Triticum aestivum L.) (Ehdaie et al, 2010) and soybean (Hansel et al, 2017). Nutrient acquisition is also highly dependent on characteristics that can be identified as the root architecture of the plant (Gregory, 2011). Researchers have developed soybean genotypes with enhanced root traits for better adaptation to soils with low soil P levels (Yan et al, 2006).…”

“…Either cases levy tremendous stress of nutrient starvation in plants. Ability of plants to withstand nutrient starvation is leveraged by a variety of mechanisms such as deeper and wider root system for nutrient harvest from soil, root exudations to solubilize fixed nutrients into available forms, root microfloral symbiosis to promote nutrient availability and better nutrient transport systems 2 .…”

Abstract

Commentary: The rapid developments in crop management and crop improvement which ran mutually complimenting paved way to 'green revolution' in several key food crops which almost eradicated famines from the face of earth. However, the best agro-management always required large quantum of agronomic inputs such as fertilizers. The modern varieties need high positive nutrient balance in the soil to throw their best yields. Currently, indiscriminate chemical inputs into agriculture either as fertilizers or pesticides has been recognized as an environmental hazard.
