Advancements in Enhancing Oil Quality in Rapeseed and Mustard: A Comprehensive Review

Rapeseed and mustard are important oilseed crops cultivated worldwide for their high oil content and versatile applications in food, feed, and industrial sectors. The quality of oil derived from these crops is influenced by various genetic, environmental, and agronomic factors. Breeding efforts aimed at improving oil quality traits in rapeseed and mustard have garnered significant attention in recent years due to their impact on market value, nutritional attributes, and industrial utility. In this review, we provide a comprehensive overview of breeding strategies and methodologies employed to enhance oil quality traits in rapeseed and mustard. We explore the genetic basis of oil quality traits, including fatty acid composition, erucic acid content, glucosinolate content, and tocopherol content, and discuss the importance of these traits for different end-uses. Furthermore, we highlight the role of molecular markers, genomics-assisted breeding, and biotechnological approaches in accelerating the breeding process and achieving targeted improvements in oil quality. The review also addresses the challenges and constraints associated with breeding for oil quality in rapeseed and mustard, including genotype-environment interactions, trait stability, and regulatory considerations. Additionally, we discuss emerging trends and future prospects in oil quality breeding, such as genome editing, metabolic engineering, and precision breeding, which offer novel avenues for achieving desired oil quality profiles while addressing sustainability and consumer preferences. Overall, this review underscores the significance of breeding for oil quality in rapeseed and mustard and provides insights into the latest advancements, challenges, and opportunities in this field. By integrating multidisciplinary approaches and harnessing the power of modern breeding tools and technologies, rapeseed and mustard breeders can continue to drive innovation and deliver oilseed crops with enhanced nutritional value, functional properties, and market competitiveness.
