Abstract

The study was conducted during the fall 2021 and spring 2022 agricultural seasons in an unheated plastic house in the College of Agriculture, Anbar University, to evaluate the performance of 12 locally produced hybrids in the Horticulture Department of the same college through full diallel cross, compared to a locally certified hybrid (Hybrid Kanz) by the horticultural department of the Iraqi ministry of agriculture. The experiment was carried out according to a Randomized Completely Block Design (RCBD) with three replications. The results showed that there were significant differences between the studied genotypes in vegetative traits and yield traits, as the hybrid 4×1 was superior in most traits, compared with certifide hybrid. In the characteristics of leaf area, the number of nodes, and dry weight of the vegetative total reached 122.83 dm2 plant-1, 38.52 node plant-1, and 84.33 g plant-1, respectively, while the hybrid 4×3 recorded the highest plant height of 284.50 cm. In traits of yield, such as the number of fruits, plant yield, and greenhouse yield, the hybrid 1×4 recorded 64.57 fruits plant-1, 5.37 kg plant-1 and 6.44-ton greenhouse-1, respectively. The hybrids 3×4 and the control did not differ significantly from the superior hybrid in plant yield and total yield. The hybrid 2×4 recorded the lowest results in vegetative traits and the hybrid 1×2 in yield traits, and no significant differences were shown in the weight of the fruit. The results showed the superiority of the 4×1 hybrid and the 4×3 hybrid in most traits, especially the quantity of them. Therefore, they are considered promising hybrids that can be produced in the conditions of anbar governorate, and the breeding and preservation of parental pure lines.
