Three open line varieties and three protogynous genotypes of Indian mustard (B. Juncea (Linn) Czern and Coss) were compared for flowering phenology and maturity period with respect to two different times of sowing and to undertaken DUS characterization by morphological descriptors for determining the extent of distinctness, uniformity/variability and stability. Results revealed that late sowing often advances early flowering and maturity duration. Out of seventeen morphological descriptors, six visually assed descriptors were monomorphic and for eleven measurable characters, three monomorphic, seven dimorphic and one polymorphic, over both the years. All the six visually assessed descriptors and eleven measurable characteristics were observed to be stable in performance over two seasons. Two out of three varieties were grouped together and clustered separately from the rest. Similarly, the protogyny plants were grouped and clustered separately from that of other varieties for measurable characters. The protogynous plants studied were clearly distinct, uniform, stable and novel from that of other varieties of brassica species.
