Evaluation of Triple Hybrids of Tomato Crop (Lycopersicon esculantum. Mill) Derived from Individual Hybrids and Some Pure line

Abstract

The study was during which the seeds of triple hybrids were produced by deriving individual hybrids by introducing 6 strains into the half-diallel cross-breeding program, resulting 15 genotypes. In the second season the hybrid seeds were planted Individuals with two strains for the purpose of developing triple hybrids. During the third season, all 48 genotypes were planted according to the randomized complete block design with three replications, service operations were conducted for the crop from irrigation, fertilization, weeding and control whenever needed. The result showed that the triple hybrid (3×1)b was significantly superior to all genotypes for the plant height reached 140.66 cm, and for the number of leaves per plant, the triple hybrid (2×1)b had the highest number of leaves over all the genotypes, which scored 137.9 leaf-1. For the number of fruits and plant yield, the triple hybrid (6×5)a showed significant superiority over all the genotypes within the experiment by recording 43.20 fruits of the plant-1 and 7.921 kg of the plant-1, respectively and the superiority of the triple hybrids (6×2)b and (5×4)a significantly over the rest of the compounds with the highest percentage of carbohydrates amounting to 10.363% and 10.325%, respectively, while the hybrids (6×5)a, (3×2)a, (3×1)a and (5×4)a recorded the highest Significant values ​​of sugars were 16.993%, 16.880%, 16.833% and 16.813%, respectively.
