Line × Tester analysis for yield and yield contributing traits

The highest value of mid parent better parent and standard heterosis over two checks AKT-101 and JLT-408 were 64.99 46.94 41.93 and 39.55% respectively for cross TBS-09 x V-21 followed by TBS-12 x V-34 (58.89 42.64 41.02 and 38.65%) TBS-05 x V-34 (53.87 41.08 33.06 and 30.83%) TBS-12 x V-21 (51.27 32.85 26.02 and 24.09%) and TBS-05 x V-21 (46.45 31.80 24.32 and 23.23%) expressed significant positive heterosis over mid parent better parent and standard checks AKT-101 and JLT-408 respectively for seed yield per plant. These highly heterotic crosses also occupied top ranks in per se performance for seed yield per plant. Hence these crosses would be exploited for isolating transgressive segregants for seed yield and its component traits for genetic improvement in sesame.
