Tissue culture induced somaclonal (SC), chemical mutagen EMS (E) and gamma ray (I) induced variation among 269 third generation families in each category generated from a popular variety of Brassica juncea were evaluated for important agronomic traits, namely flowering time, plant height, number of primary and secondary branches, seed yield per plant and per plot. The frequency of somaclonal-lines significantly superior to control was higher than such EMS or irradiated lines, in general. Somaclones also showed higher heritability values. One somaclone, SC-122, is significantly superior to control for upto five traits, simultaneously, demonstrating the practical utility of somaclonal variation in improving productivity.
