The major activity of the group is genetic improvement of oilseed mustard (Brassica juncea) through conventional and biotechnological approaches. The major achievement of the group in the form of tangible products has been development of several hybrids in mustard such as hybrid DMH-1 and DMH-4 which are under cultivation in the farmers’ field. The group has also developed a transgenic mustard hybrid DMH- 11 that has been cleared by the Technical Committee of the Ministry of Environment & Forest. The group is also actively engaged in research on molecular mapping and marker-assisted breeding in mustard.

Several bi-parental molecular maps have been developed and used for mapping of important traits pertaining to oil and meal quality, disease resistance and yield traits. Some of these traits on oil and meal quality and disease resistance have been diversified to important Indian cultivars by marker-assisted backcross breeding. The group is handling a Centre of Excellence on genome mapping and molecular breeding in Brassicas funded by Department of Biotechnology (DBT), Government of India and is running in to Phase II. Under this programme several important mustard lines have been sequenced by NGS. Sequence information of these lines are being used to develop a breeding chip in mustard for undertaking faster marker-assisted breeding. Recently, a DBT-UDSC Centre had been established with the group for undertaking advanced breeding in mustard.
