Abstract

The aim of the present research is to predict the phenotypic description of Queen's commercial hybrid parents. In this research, the Queen variety (salad tomato) was cultivated as a desirable cultivar in Iran during 2022. In the following year (2023), after selfing, the seeds obtained from the ripe fruits of this variety were collected and planted again with hybrid seeds, and their desired traits were recorded. Based on the similarity with the parents, genotypes 10, 22, 23, 32, and 48 were selected for component 1, and genotypes 1, 2, 11, 14, 15, 21, 28, 38, 42, 43, 45, 47, 53, 54, 58 and 74 were selected for component 2. The Queen hybrid was expected to be obtained from crossing individual plants similar to these groups. Among the candidate individuals, and according to the simulation of qualitative traits and the genetic distance between individuals (considered the maximum distance for hybrid production), we expect genotype 22 to be the most similar plant to one parent and genotype 1 and 2 to another parent. These genotype progenies were considered for future developement to reach recombinant inbred lines and finally hybrids similar to Queen.
