Study of genetic analysis of individual hybrids derived by the half-diallel cross of some Lycopersicon esculantum mill

The study was conducted for the first season of 2020 in field College Agriculture \ Diyala University which seeds generation F1 hybrids were produced six strains that selected according to genetic distance among them and resulted 15 by applying half diallel crossing program. In second year, individual planted with their parents a hybrid Commercial common boob cat comparison within experiment evaluate performance these design complete randomized sectors three replications. differences tested LSD test. result showed highest strength compared trait plant height 43.34 cm, number fruits 48.20%, yield 77.27%, TSS ratio 41.83%, fruit content vitamin C 33% sugar 25.86% above traits, respectively.
