Genome editing technology like the CRISPR/Cas9 has emerged as an excellent and rapid plant breeding tool for exploring basic plant biology as well as for increasing agricultural GDPs. Although CRISPR-based genome editing had shown its applicability in different plant genomes since 2013, the genus Brassica has come across this precise gene modification tool only since 2015. In polyploid Brassica species, CRISPR/Cas9 technology has been established for the functional validation of novel genes as well as for improving various agriculturally important traits including the enhancements of seed numbers and oil contents. The talk will discuss CRISPR/Cas9 genome editing reports published exclusively towards enhancing the oil quality traits in Brassica species. While doing so, the talk will also succinctly discuss the possibilities and challenges for overcoming its shortcomings in the case of polyploid crops. Additionally, the talk will bring about the opportunities that remain open for targeting the key desired traits towards fulfilling the breeding milestones of the Indian oilseed mustard Brassica juncea.
