Carrot (Daucus carota) is a vital root vegetable globally, valued for its nutritional content and economic importance. However, carrot production faces challenges from diseases and the need for higher yields. Traditional breeding methods have been effective but are time-consuming and less precise. Marker-assisted selection (MAS) offers a modern approach to accelerate breeding for high-yield and disease-resistant carrot varieties. This study explores the application of marker-assisted selection in breeding high-yield and disease-resistant carrot varieties, highlighting the advancements and key findings in this field. Results reveals that MAS has significantly improved the efficiency of breeding programs by enabling the precise selection of desirable traits at the seedling stage. Additionally, the integration of MAS with other modern techniques such as CRISPR/Cas9 has shown promise in developing disease-resistant crops rapidly and efficiently. The sequencing of the carrot genome has further facilitated the identification of key genes for disease resistance and yield improvement, providing a robust foundation for future breeding efforts. The application of marker-assisted selection in carrot breeding holds significant potential for developing high-yield and disease-resistant varieties. This approach not only accelerates the breeding process but also ensures the precise incorporation of desirable traits, thereby enhancing crop productivity and resilience. The integration of MAS with genomic tools and advanced breeding techniques will likely continue to drive innovations in carrot breeding, addressing both current and future agricultural challenges.
