Abstract:
The experiment was carried out at the College of Agriculture in Diyala for the seasons (2021-2022) and (2022-2023), where eleven strains of cherry tomatoes were imported from the Tomato Genetic Resources Center (TGRS) at the University of California and the Davis Institute and planted in the first season.. pure tomato lines (LA2838, LA3002, LA4355, LA0797, LA7371, LA4451) and their codes (1, 2, 3, 4, 5, 6) were chosen respectively and entered into the half-cross breeding program to produce individual hybrids, and in the season The second included an experiment to evaluate the genotypes (6 parents, 15 hybrids) according to the split-plot system, in a completely randomized block design, with three replicates, and spraying with boron at a concentration of (0, 100 mg.L-1). The results showed that there were significant differences with spraying with boron, as the parent showed LA2838 ( 1) It was superior in the number of leaves, fruit length, number of total fruits, and production per plant. Father LA4451 (6) showed superiority in the number of leaves, Father (5) LA7371 showed superiority in the set percentage, and Father LA0797 (4) showed superiority in the number of branches with spray levels. With boron at a rate of 100 mg.L˗ˡ. As for the hybrids, they showed significant superiority in characteristics, including the number of leaves, the number of branches, plant production, the percentage of knots, the number of fruits, and the length of the fruit, respectively, for the hybrids (6×1), [3×1], (5×3)], and (5×3). ) and (5×2) and (2×1) and (4×2). The hybrids showed [(6×1) and (4×1)[ and (6×4) and (4×2) and] (2×1) and (3×1) [and (6×1)] and (5×2) and [(3×4) and (×42) and (2×1) [overlap in the level of boron spraying at concentration 100 It was superior in moral characteristics in the number of leaves, the number of branches, the length of the fruit, the number of total fruits, the percentage of knots, and plant production.
