Translating High-Throughput Breeding into Frugal Field Solutions: A Review of Integrated Genetic, Microbial, and Seed Priming Approaches for Marginal Environments

Abstract

High-Throughput Phenotyping (HTP) has revolutionized plant breeding in developed nations, utilizing automated gantries, advanced drones, and spectral sensors to capture genomic performance with unprecedented precision. However, the "phenotyping gap" persists: while the Global North accelerates genetic gain via "Big Data," smallholder farmers in the Global South remain disconnected from these advancements, often growing varieties ill-suited to their hyper-local microclimates. This review protocol, "Translating High-Throughput Breeding into Frugal Field Solutions," explores the democratization of phenomics through the concept of "frugal innovation." We analyze the shift from expensive centralized platforms to decentralized data collection tools based on smartphones (e.g., Field Book, OneKK) and low-cost remote sensing (e.g., nanosatellites). By leveraging the ubiquity of mobile technology, we can transform smallholder fields into a distributed network of research stations, enabling "Citizen Science" based breeding. This document will detail how frugal tools can increase selection intensity and accuracy —two pillars of the Breeder’s Equation—in resource-constrained environments, ultimately bridging the gap between elite genomic research and farm-level reality.
