A set of 21 mechanical diallel varietal mixtures involving seven parental components of lentil was made to assess their extent of superiority over better-parent (BP), mid-parent (MP) and standard variety (SV) for yield and yield-contributing characters. The maximum magnitudes of superiority over BP, MP and SV for seed yield per plant were observed to be 18.5, 26.4 and 30.6 percent, respectively, in Pant Lentil 234 + Lentil Hisar 84-8 mixture. Superiority over BP indicated that harvest index, primary branches per plant and seeds per pod were among the most responsive characters in varietal mixtures. Mixtures that showed superiority for seed yield per plant were not superior for all the characters; however, mixture of Pant Lentil 234 + Lentil Hisar 84-8 exhibited superiority for days to 75 percent flowering, nodes up to first flower, fruiting nodes per plant, 100-seed weight and harvest index along with seed yield per plant over standard variety
