Heterosis studies for yield and its attributes in Lentil (Lens culinaris Medik. L)

Abstract

The breeding material for the study comprises of fifteen crosses involving eight divergent parents including three lines (female parent) viz, L 4076, JL 3, IPL 81 and five testers (male parents) viz, RL 7, EC 267554, LL 4710, L 4717, EC 267583, and L 4717 grown in a Randomized Complete Block Design with three replications. The eight diverse genotypes were crossed in line x tester mating design following the method given by Kempthorne (1957). Data collected were subjected to analysis for heterosis. Heterosis was found significant positive for all traits except for days to maturity noted with significant and negative under study. Significant positive heterosis better parent found in nine crosses viz, JL 3×RL 7, IPL 81×EC 267554, JL 3×EC 267554, IPL 81×RL 7, L 4076×EC 267554, L 4076×L 4717, JL 3×L 4717, L 4076×EC 267583 and L 4076×RL 7 for seed yield plant-1 revealing its significance in future crop improvement programme.
