Abstract:
A Line × Tester analysis in sesame (Sesamum indicum L.) was carried out with four lines and six testers to estimate the combining ability effects and heterosis for thirteen characters viz., days to first flower, days to 50 per cent flowering, days to maturity, plant height, number of branches per plant, number of capsules per plant, capsule length, width of capsule, number of seeds per capsule, 1000 seed weight, shattering percent, oil content and seed yield per plant. Based on the general combining ability effects, RT-54 among lines and SSD-22 among testers and for oil content among lines RT-54 and among testers AT-255 were found to be good general combiners for seed yield per plant. The cross combination GT-3 X AT-255 exhibited the maximum positive and significant sca for seed yield per plant and the cross RT-54 X MT-10-8-2 showed maximum positive significant sca effect for oil content and hence recommended for heterosis breeding, whereas the hybrid GT-3 X AT-255 exhibited high test weight and hence it is recommended for breeding bold seeded type. Similarly the hybrid PRAGATI X AT-255 recorded desirable sca for earliness.
