Abstract: The investigation was carried out 1rith sLT parents (3 bi/ornlar and 3 tetralocul  and  18 recombinant lines (F1~) which were grmrn i11 three replications following  Randomized  Block Desig11 at instructional Farm, Bidhan Cha11dra Krishi /vishvidhyalya  Jaguit . West bangal during the year 2007-2008. Same parwts a11d 18 recombinant lines (F5J H'ere gro\1'11 in the follmring year in the same procedure. The prime objectilve'e of the study Has to study the relationship of yield with yield components among parents and recombinant lines in Brassica campestris l. Var. y'ellow Sarson to carry 011tfuture research programme. Eleven characters were  studies during both the years. Seed yield per plant recorded signiJlcant positive correlation only ll'ith two characters siliqua on branches and total si/iqua per plam among the parents in the second year white no  significant relationship was recorded between seed yield per plant and other yield  attributing characters among the parents in the first year. Seed yield per plant showed 110 significant correlation with any of the characters among F~ recombinant lines. fn F, seed yield per plant showed signiJ/cant positive correlation 1rith four chamcters plant height. siliqua on main
