A Scopus-based bibliometric analysis of research into impact of drought on durum wheat plants was performed. A corpus of 865 documents published from 1946 to 2025 was retrieved. Temporal and regional patterns, most relevant institutions, authors, keywords, and publications are discussed. From the exponential growth model, the annual growth rate for the number of publications over the entire period was 8.23 %, with R2 of 0.86051. Italy was identified as the greatest contributor among countries. H-, G-, and M-indices were employed to analyse authors ratings. Frontiers in Plant Science was detected as the most important journal in this field of research. Using the Sankey diagram, the relationships between author country, author affiliation, and individual authors were considered. Major steps of keyword evolution are analysed. The keywords “yield” and “water stress” in the Trend topic chart indicate areas of persistent research interests. The terms “climate change”, “abiotic stress”, “physiological stress”, and “plant proteins” indicate future research directions. Review of the most-cited articles outlined major themes in the ‘response of durum wheat to drought’-related literature, with a shift from assessing drought-inflicted yield losses to elucidation of molecular mechanisms of drought resistance. Analysis of time-sliced co-occurrence maps of keywords demonstrated the genesis of the “biochemical/genetic” cluster, which was later transformed into the “systems biology” cluster. Bibliometric mapping of keywords is scrutinized through the lens of the development of the ‘drought in durum wheat’ research. The most influential publications were detected, with summarising major findings.
Keywords: Triticum durum, abiotic stress, aridity, Biblioshiny, research hotspots, temporal and regional patterns, co-occurrence maps
