THE POTENTIAL OF TOMATO F2-HYBRIDS FOR PROCESSING |
| Authors: | N. Kedar, J. Adler, H. D. Rabinowitch |
| Abstract:
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. | |
