Toria is the predominant oilseed crop of Assam, but productivity is very low compared to all India average. Therefore, continued efforts are necessary to achieve high seed yield through breeding high yielding varieties. The present study was conducted to evaluate the segregating populations of some toria x yellow sarson crosses for yield and related traits. During Rabi 2015-16, 21 populations consisting of 5 parents, 3 F1s and 13 F3s were grown. Highly significant differences were observed among the populations for different yield attributing characters. High genotypic variation was observed for number of secondary branches per plant, seed yield/plant, biological yield/plant and harvest index. High heritability was observed for days to 50% flowering, seed yield per plant and plant height. High genetic advance was recorded for number of secondary branches, seed yield/ plant, biological yield/ plant, harvest index and days to 50% flowering. Jeuti was early maturing genotype. The genetic variation present in toria and yellow sarson populations could be utilized in breeding useful varieties of toria and yellow sarson types.
