Analysis of tomato lines combining ability by productivity traits for selecting acceptable parents when developing tomato hybrids

Combining Ability Estimates for Yield Some Traits in Tomato (Lycopersicon esculentum L.) by Line×Tester

     12 single crosses (F1) achieved by combining four testers and three commercial lines of tomato were evaluated for their response to water deficit stress and the combining ability of yield and some yield components. The layout was split plots according to randomized complete block design with three replications and three irrigation levels (FC, 60%FC and 40%FC). Crossing among lines and test...

Implications of heterosis and combining ability among productive Single cross hybrids in tomato

Ten tomato commercial and productive single cross hybrids extensively grown in Northern Transitional Zone of Karnataka were planted in the field at UAS, Dharwad following RBD design with three replications. A 10 x 10 diallel set was generated by crossing these single cross hybrids in all possible combinations (excluding reciprocals) and 45 double cross hybrids were planted during February, 2007...

Diallel Analysis for Lycopene Content in the Hybrids Derived from Different Colored Parents in Tomato

Lycopene is a red pigment in tomato with purported antioxidant properties. As the amount of lycopene has been reported to differ in different colored tomatoes or even absent in non-red tomatoes, the objective of this study was to investigate the inheritance of lycopene content and the color parameters of hybrids using a 10 parent diallel excluding reciprocals. Parents differed in general combin...

Cytogenetic Notes on Tomato Species and Hybrids.

Since Lycopersicon was separated from the closely related Solanum, the species of tomatoes have been reduced by taxonomic revisions to six (MULLER 1940) or seven (LUCKWILL 1g43), all probably indigenous to the West coast of South America or the adjacent Galapagos Islands. These species are naturally divided into two sections or subgenera: I. EULYCOPERSICON, containing the two edible and widely ...
