Abstract

Abstract The experiment was carried out in the greenhouses of the extension farm in Diyala governorate for the seasons (2020-2021) and (2021-2022), where ten strains of cherry tomatoes imported from the Tomato Genetic Resources Center (TGRS) at the University of California Davis Institute were planted in the first season. Tomatoes were selected (5 ) pure lines (LA4451, LA4753, LA3334, LA3538 and LA4689) and their symbols (1, 2, 3, 4 and 5), respectively, and entered into a Full Diallel crossing program to produce individual hybrids, and in the second season it included an experiment to evaluate the genotypes (5 parents + 20 hybrids) according to the RCBD design and with three replications, and the results were as follows: Genotypes: There was a significant effect of genotypes, as the parent (1) outperformed in the average fruit weight, per plant yield and total yield (8.41 g, 2.72 kg and 3.40 tons), respectively. The parent (2) outperformed the contract (94.11). parent (5) was superior in the number of flowers in the inflorescence, the number of total flowers and the number of fruits per plant (82.66 inflorescences. plants, 937.00 flowers. plants, and 512.33 fruits. plants). The hybrid (1×4) was also significantly superior in the percentage of the fruit set (95.13), the average fruit weight, the yield of one plant and the total yield (13.45 g, 4.66 kg and 5.82 tons, respectively). While the hybrid (2×5) was superior in the number of total flowers (941.33 flowers). Hybrid (5×2) outperformed in the number of flowers in the inflorescence (90.00 flowers). The superiority of the hybrid (5×4) in the number of fruits (521.33 fruits). Genetic analysis: The hybrid (1×5) showed desirable and significant hybrid vigor for the characteristics of the number of flowers in the inflorescence, the number of total flowers and the number of fruits in the plant). It was also found that the hybrid (5×2) showed a significant hybrid strength for the two traits (one plant yield and total yield). While the hybrid (2×5) and (5×1) recorded the strength of the hybrid for one trait for each of them (the percentage of the knot and the average weight of the fruit) respectively for the best parents.
