ABSTRACT
Twenty four crosses combinations were developed by line × tester mating design and evaluated hybrids, parents along with check during rabi 2015-16. Results indicated that more hybrid vigour for total fruit yield and most of the yield components in tomato. The crosses viz. Podlandt Pink × Sioux, AR-29 × Sioux, Tommy Toe × UK Local-2, Bony Best × Sioux, Bony Best × UK Local-2 and Black Prince × UK Local-2 showed positive significant heterosis over commercial check for yield per plant. The cross exhibited significant heterosis over commercial check was Tommy Toe × UK Local-2 for plant height and number of primary branches per plant; Bony Best × UK Local-2 for number of fruits per cluster; Podlandt Pink × Sioux and Black Prince × UK Local-2 for number of fruits per plant.
Key words :
Commercial check, Heterosis, Heterobeltiosis, Tomato, Yield attributes.
