Route Analysis Through Filial Generations of Modern Varieties of Tomato (Solanum lycopersicum L.)

Objective: To measure the efficiency of using advanced generations some commercial tomato hybrids for small farmers and to identify most important yield components associated with yield. Design/Methodology/Approach: Seven saladette-type indeterminate growth were evaluated, as well their respective F2s F3s under greenhouse conditions. The evaluation three was carried out during 2013 agricultural cycle. Three harvests made at 82, 94 136 days after transplanting. experiment a randomized complete block design, 4 replications 10 plants per replication. Results: Results indicated that there significant differences few traits in F2 F3. Path analysis showed total number fruits had highest direct indirect effects on through generations. Limitations study/implications: usefulness would depend genetic background parental lines take part such hybrids, present high inbreeding depression depending composition progenitors. Findings/Conclusions: Advanced ‘LORETO’, ‘CUAUHTÉMOC’ ‘ESPARTACO’ could be used by growers since low values observed F3 families
