Heterosis over better and standard parent was estimated for yield and its components in 30 hybrid lentils (Lens culinaris Medik.) derived by crossing three well-adapted varieties at testers and 10 eco-geographically diverse genotypes as lines. The range of heterosis over better parent (in percentage) was -10.1 to 49.9 for days to initial flowering, -16.6 to 33.7 for plant height, -17.1 to 21.0 for primary branches/plant, -16.7 to 42.7 for secondary branches/plant, 16.7 to 42.7 for secondary branches/plant, -24.7 to 81.7 for pods/plant, -11.1 to 15.8 for seeds/pod, -48.8 to 19.6 for 100-seed weight and -23.5 to 106.4 for yield/plant. The majority of crosses exhibited negative heterosis over better parent for 100-seed weight. The heterosis observed for yield was mainly attained through major yield components, pods/plant and secondary branches/plant. The hybrid Pusa 4 x Pant L-234 exhibited maximum better and standard parent heterosis for yield/plant, and also showed highest better parent heterosis for pods/plant along with high heterosis for seeds/pod and 100-seed weight
