ABSTRACT
To exploit heterosis in cucumber, six lines were crossed with three testers to develop 18 F hybrids. All the 1 hybrids along with their parents were evaluated and line x tester analysis was carried out. Heterosis for total fruit yield per vine was the highest in KC-3 x KML which exhibited 12.75 per cent over the best parent and 38.84 per cent over commercial check (F hybrid) followed by KC-1 x KML. The entries KC-1, KC-3 and KC-4 were identified as good general combiners for total fruit 1 yield per vine. The crosses KC-1 x Poinsette, KC-3 x KML and KC-1 x KML had significant sca effects for fruit yield per vine.
Key words :
Combining ability, cucumber, Cucumis sativus, fruit & yield parameters, gca effects, heterosis, sca effects.
