| Abstract:
New tomato hybrids suitable for different production trends have been obtained using positionally sterile and fertile tomato lines with a high general combining ability for the most important economic traits. Desirable characteristics included semi-determinant for plastic hothouses, and semi-determinant and indeterminant for early and middle-early field production in supporting constructions. The new semi-determinant hybrids exceed standards Balca and Balkan concerning earliness, size (slightly) and firmness, but are balanced concerning total productivity. A new indeterminant tomato hybrid (Viki F1) for middle-early field production has been created which has a fruit which is more balanced, standard and hardier in longer-term storage than those of standards Kristi and Carmello. Seed production of the new hybrids is carried out on a sterile base and a genetic marker. This makes the emasculation of the mother parent flowers easy and guarantees a high purity of the hybrid seeds. | |
