THE POTENTIAL OF TOMATO F₂-HYBRIDS FOR PROCESSING

The high cost of F₁-hybrid seed will probably not allow their use in developing countries and in direct seeded fields in general.
F₂-hybrids obviously would be more economical if disease-resistant, heterotic and fairly uniform combinations could be found.

In replicated trials 10 lines were compared: three VF and 1 VFN parent, 3 F₁ and 3 F₂-combinations between the nematode resistant and the VF parents, In nematode infested soils one of the 3 F₂-hybrids greatly outyielded the 4 parent lines and was only slightly inferior to the corresponding F₁-hybrid.
In non-infested soils, the F₂-hybrids were either similar or susperior to the nematode resistant parent.
The uniformity of some F₂-hybrids was satisfactory.

Advantages and limitations of F₂-hybrids for processing are discussed.
