| Abstract | ||||
| A half-diallel cross was performed among six cultivars of tomato. Then parents, 15 F 1 and 15 F2 were evaluated during the two late summer seasons of 1999 and 2000. The obtained results could be summarized as follows: Heterosis over the mid-parental points was significant with a positive value of 13.6% for plant height; heterosis over the better parent was absent for plant height, while heterosis over the mid parent was absent for all studied traits while inbreeding depression was significant with a positive value for ascorbic acid; cultivar Peto 86 was good combiner for number of branches per plant and fruit firmness; cultivar Fla 7324 was good combiner for plant height, total soluble solids and ascorbic acid content; cultivar VF 145-6-7879 was good combiner for fruit firmness and total soluble solids; LHT 24 cuttlvar was good combiner for total soluble solids and ascorbic acld content; Fresh Market 9. was good combiner for ascorbic acid content, Heritability in broad sense was high for fruit firmness, total soluble solids and ascorbic acid content: heritability in narrow sense was intermediate for fruit firmness and low for the other studied traits. | ||||
