| dc.description | "Rice (Oryza sativa L.) is a cornerstone of global food security, providing a primary dietary energy source for over 3.5 billion people and accounting for approximately 20% of global caloric intake (Wing et al., 2018). As the global population is projected to reach 10 billion by 2050, the demand for rice is expected to intensify, particularly in Asia and Africa, which are already facing significant yield constraints due to salinity stress (Zheng et al., 2023; Clay et al., 2024). Coastal and deltaic rice-growing areas of Asia, which collectively account for 65% of global rice production, are increasingly vulnerable to saltwater intrusion driven by sea-level rise, tidal surges, and climate-induced hydrological changes (Wassmann et al., 2009; Al-Tamimi et al., 2016). Salinity levels exceeding 4 dS/m (decisiemens per meter) can reduce rice yields by more than 50%, posing a severe threat to food production in these ecologically fragile areas (Mohanavelu et al., 2021; Melino and Tester, 2023). Developing salt-tolerant rice varieties is widely recognized as the most sustainable and cost-effective strategy to mitigate salinity-induced yield losses (Khanna et al., 2024). National and international breeding programs have made notable progress in this direction (Ismail and Horie, 2017). In parallel, advances in molecular genetics and genomics have led to the identification of numerous salinity-responsive genes and quantitative trait loci (QTLs) (Ismail and Horie, 2017). However, translating these discoveries into elite, farmer-preferred cultivars has been largely unsuccessful (Hu and Schmidhalter, 2023). Furthermore, despite the availability of promising genetic resources, their deployment in breeding pipelines has not led to widespread adoption or impact at the farm level (Melino and Tester, 2023). A significant constraint underlying this translational gap is the continued reliance on phenotypic screening under highly controlled, idealized conditions-typically in hydroponic systems, greenhouses, or growth chambers (Mittler, 2006; Munns et al., 2006; Araus and Cairns, 2014; Gilliham et al., 2017; Negrão et al., 2017; Liu et al., 2022; Rawat et al., 2022). To accelerate the development of salinity-tolerant rice varieties and improve the translational efficiency of genomic discoveries, a fundamental shift in phenotyping strategy is required (Tracy et al., 2020; Moshelion et al., 2024). In this viewpoint, we introduce a novel field-based phenotyping platform specifically designed to overcome the limitations of conventional, controlled-environment screening. This platform enables the evaluation of rice genotypes under ecologically realistic salinity stress conditions that closely mimic those encountered in farmers’ fields. Crucially, it allows the identification of genotypes with stable performance under complex field conditions, traits that are often overlooked in reductionist settings. This approach represents a critical advancement in bridging the gap between laboratory discovery and field application, offering a scalable and scientifically rigorous pathway to deliver resilient, high-performing rice cultivars to salt-affected regions." | |
