Combining Ability Yield Attributing Characters in Line x Tester Inter specific Hybrids Confirmation
19
In this experiment, 92 (YHB trial) interspecific
crosses (
G.hirsutum x G.barbadense
) along with three
checks (MRC 6918
Bt
check, RAHB 87 and DCH 32
non
Bt
checks) were subjected to Line x Tester
analysis (23 hirsutum testers and 4 barbadense lines).
This experiment was laid out in Randomized Block
Design (RBD) with two replications. Each entry was
sown in 2 row plots spaced at 90 cm x 60 cm with
recommended dose of fertilizer and seeds were sown
on 28-6-2010, 2-3 seeds were dibbled per spot in each
row and thinning was attended to retain one healthy
plant per hill at 25 days after sowing. All the
recommended package of practices were followed to
raise healthy crop.
