Genetic Studies in Carrot (Daucus carota L.): Advancements and Trends in Research

Abstract

The cultivated carrot (Daucus carota L. subsp. sativus) is a globally important crop valued for its high content of beta-carotene, vitamins, and other bioactive compounds. Advances in molecular genetics and genomics have driven improvements in yield, stress tolerance, disease resistance, pigment accumulation, and nutritional quality. Here we present a comprehensive scientometric analysis of 398 peer-reviewed articles on carrot genetics (1964–2023), integrating keyword co-occurrence mapping and co-authorship network analysis to identify research lines, methodological approaches, and international collaboration. The focus of research was predominantly on Plant Biology (67.59%), followed by Conservation (15.58%) and Plant Breeding (10.55%). The integration of omics technologies has yielded new insights into abiotic stress tolerance, carotenoid and anthocyanin biosynthesis, and genetic diversity; however, significant challenges remain in translating genomic resources into routine breeding practice and conservation of genetic resources. We recommend prioritizing genome-assisted breeding strategies, functional genomics and interdisciplinary, multi-omics approaches to accelerate the development of resilient and high-quality carrot cultivars under climate change.
