Tomato Traits Improvement for Multi-Circle Hydroponics with Target Hybridization

The effectiveness of target hybridization techniques was evaluated in this paper. Productive maternal plants with larger-sized fruits and early ripening dwarf paternal plants were involved in the target crossings. F₁ hybrids and their F₂ progeny resulted from the self-pollination of F₁ plants were produced. Tall plants and dwarf plants of the F₂ population segregated strictly by Mendel’s low (3:1). With help of dispersion analysis six parental forms and three hybrids, we selected the more productive plants with large fruit sizes among the dwarf plants, then obtained the seed progeny of these selected plants and studied the heritability dwarfism and large fruit size, in F₃ hybrids. It was confirmed that crossing between tall maternal forms with large fruit size and dwarf early ripening paternal forms leads to a reduction in plant height to the dwarf father. These traits were maintained in F₃. Therefore, the dwarfism of Solanum Lycopersicum L., which is needed for multi-circle hydroponic technology, is inherited from the parental type, and the fruit weigh is inherited from the maternal type. To obtain new tomato forms for multi-circle hydroponics, maternal plants with large fruit and dwarf paternal forms must be crossed.
