Androgenic lines of Brassica juncea cv. PR-45 raised by anther culture, were screen for genetic variation. 393 androgenic plants were transferred to pots to study the R0 generation. These plants showed substantial variation for different characters. Seed progenies of 27 lines of R0 plants were sown in the field to study R1 generation. Androgenic plants within lines were significantly homogeneous for the various agronomic characters studied. Two lines were shorter (18 - 20 %) than the control plants, with a remarkable feature of early maturation. Three lines showed 27 - 31 % higher yield than the parent cultivar.
